      • 40. Re: Acrobat X Wont Start

        I had the same issue with CS6 Master Collection on a WIN 7 64x machine. Acrobet would not start but I could see it appear in the Task Manager for a few second and the disapear. Without the Task Manager, it seem like nothing was happening. I tried manually install the latest patch, but it would not fix. So I end up clearing the C:\Program Files (x86)\Common Files\Adobe\Adobe PCD Folder. After that, it ask me to accept the license and it worked again...


        Hope it helps releasing a fix!


        thanks, Frank

          I have the same problem. At this point I uninstalled CS5 to keep only CS6 and will try the reinstall Acrobat X pro and clear some files like sugggested.

            Same issue here. Unacceptable, Adobe. Unacceptable!

            • 43. Re: Acrobat X Wont Start

              exactly the same case - did reactivate as you instructed - now it works OK, thanks for the tip

              • 44. Re: Acrobat X Wont Start

                Dealing with the same issue also.


                I completely uninstalled Master Collection CS5.5 before installing Master Collection CS6 (Windows 7 x64 Pro). (NOT USING CS5 or CS5.5 at all once i starting using CS6).


                (exactly 30 days later with no warning, just a random quit of Acrobat X).


                The program will not load now at all.


                I will try to deactivate and reactivate.


                Something is not adding up here.

                  Deactivation/Reactivation fix seemed to work...for now.


                  I have to say i'm really disappointed here. It seems like Adobe doesn't even recognize the full extent of the problem.


                  Maybe i've just been lucky, but this is the first time i've had to post/deal with an Adobe bug like this.

                      @Manish-Sharma #37 The link to this problem does not apply in any way to my situation. I installed CS6 on a brand new machine that never had CS5.5 on it. I still have the failure to launch problem with Acrobat X. I did do the deactivate/reactivate procedure (without deleting the cache file) and it is working for now. Do I need to wait 30 days to see if it is going to reappear?

                            Matt:  Thanks for posting your chat dialog.


                            To all others, the important issue prior to deactivation is to MOVE THE CACHE FILE from the folder specified in Matt's dialog to the desktop.  This is what allows the deactivate link to appear in the help menu on Photoshop.  If you don't move the cache file, you won't be able to deactivate.  The cache file is automatically recreated when you reactivate Photoshop.   You can then delete the cache file FROM THE DESKTOP.


                            Thanks again Matt for posting.

                              I am glad it is helping some people out.


                              I'd figure it would be best to post the official support answer so that everyone knows it's legit. 


                              So many people have answers but being in a large company, we cannot afford to guess which is a proper fix.


                              So we went direct!

                                Following the deactivation of photoshop and reactivating worked for me as well....Thanks Matt


                                • 53. Re: Acrobat X Wont Start

                                  I am so glad to have found this forum, Acrobat X just stopped working for me also.

                                  I am on a Windows 7 64-bit, most recent service pack system.

                                  Before I installed Design Premium CS6, on May 26th, I completely removed CS4 and CS5.5 except for the serial numbers, and ran a totally cleanup on my system.

                                  It installed and has worked flawlessly until today.

                                  I did the deactivate and reactivate function and Acrobat X now works, but instead of actually running the executable and opening the program I get the dialogue box asking if I want to run this program each and every time I open either the program, or a pdf file.

                                  Does anyone have a fix for that issue?  I will try uninstalling and re-installing just Acrobat and see if that corrects the issue, will post results when done.

                                    That sounds a lot like UAC or user account control in windows which asks if you want to run this program. I usually turn that off in windows as it kind of bugs me...of course microsoft says you shouldn't. This is of course if Acrobat does actually open when you say yes.

                                      Thanks Mike, I turned it off and it does fix the problem, as yes, the program opens when you select yes.  Unfortunately it is a global change, you cannot select that option for just Acrobat.  Will try removing just Acrobat and reloading next.

                                        There are ways to still have UAC on and get rid of the message. Sometimes right clicking the exe file for acrobat or other programs and selecting run as administrator will resolve this.

                                        There are other hacks out there as well. If you google UAC your going to find a wealth of info on it. Reinstalling Acrobat may resolve the issue, but it could popup for other programs later.


                                        Anyways, hope it works out for you!

                                          Mike, thanks for posting the additional information, right now I am under a tight production deadline and keeping fingers crossed that Photoshop, InDesign and Illustrator stay stable.  Will definitely pursue the other possibilities when I get the chance!

                                            Hi ,

                                            I had posted the workaround on another thread: http://forums.adobe.com/message/4529681#4529681    .... reposting here.

                                            For all the users who have faced a problem where Acrobat did not launch after 30 days of serializing with a suite serial number, please execute the following workaround:


                                            1. Make sure you are connected to the internet.
                                            2. Launch a regular  CS6 product other than Acrobat or Flash Builder (for example: Photoshop, After Effects, Premier Pro, InDesign, Flash Professional, Illustrator, Dreamweaver.)
                                            3. Click on Help->Deactivate .
                                            4. Deactivate the application. Quit application.
                                            5. Launch a regular  CS6 product other than Acrobat or Flash Builder (for example: Photoshop, After Effects, Premier Pro, InDesign, Flash Professional, Illustrator, Dreamweaver.)
                                            6. Accept Eula.
                                            7. Register trial by signing in. Let the app launch.
                                            8. Quit and relaunch the app. Wait for UI to come.
                                            9. Click on License This Software button on the UI.
                                            10. Click on Sign in .
                                            11. Serial number screen will come
                                            12. Enter the serial number in the serial number screen and click Next.
                                            13. Quit app and relaunch the app while connected on the internet .


                                            After this if you launch Acrobat it will launch and run forever without trouble. In case you still face a problem , try relaunching the other CS6 app once more and then launch Acrobat.


                                            Feel free to send me a private message if you need any more help with this.

                                              In my office we have some nfr licenses and, for policy, some computers have installed only Acrobat X of the CS6 suite (no Photoshop ecc...). There is a workaround in this situation?

                                                I originally had this issue because I had CS5 with a stand-alone license for Acrobat X. But the deactivation and reactivation work. However on OSX, Acrobat is launching when a PDF's is opened but never actually opens the PDF. I have to open thefile via the menu system. Same goes for closing, it wont cloase the PDF by click the X button. I literally have to goto the menu system in Acrobat to close it. I think somehwere along the way it got corrupted. I've tried reinstalling several times now.

                                                  I've had exactly the same issue with Acrobat X Pro today. I followed the transcript Raghu - Matt.

                                                  The issue seems to have been resolved now.

                                                        Thanks Matt, this worked great! We were experiencing a similar issue, but instead of Acrobat not opening at all, it would open for a few seconds but then the Adobe Software License Agreement would pop up and instantly close Acrobat. Clicking Accept would then open Acrobat back up, but 5-10 seconds later it would close, and the License Agreement window would popup again. It would just keep doing that in an endless loop. But your chat fix did the trick for us!!! Thanks again!!!

                                                              On the Mac, in the applications folder are CS6 apps downloaded from Creative Cloud, and inside each products folder is that products uninstaller. That is the uninstaller I used the first time to remove Acrobat X Pro.


                                                              After removal by that means, Acrobat Application Manager was still verifying that my removed app was still installed. There was no way to reinstall (Acrobat).


                                                              What I was told by the chat tech I chatted with was to got to Applications > Utilities > Adobe Installers Which is from where he recomended I do all my uninstalls.


                                                              So, from there I clicked on Acrobat X Pro and followed the screen instructions.


                                                              When I then launched Adobe Application Manager, teh Install button next to Acrobat was active and I was able to reinstall Acrobat.


                                                              Because after removing a previous version of CS, my photoshop CS6 app was announcing a missing file and that I needed to uninstall and reinstall Photoshop - more an annoyance than an actual necssity since Photoshop CS6 was working fine despite the notification window alerting me to a missing file Photoshop needed to operate... Since the uninstall and reinstall of Acrobat went so well, I followed suit with Photoshop CS6, removing it from the Applications > Utilities > Adobe Installers folder. When I launched AAM, the install next to Photoshop was available. I downloaded it and intalled ... everything is working fine.

                                                                It works temporarily... but then stops working 30 days later, as I have just found out.

This will be made available as soon as possible (hopefully by later today). One of the solutions discussed here was to delete the cache.db file. This is *NOT* a recommended solution. Please use the solution marked as correct on page one of this thread instead. Sorry for the inconvenience.

If you are facing the issue, you need to deactivate from one of the other CS6 products such as Photoshop (Help > Deactivate) then launch that product again and sign in with your Adobe ID. Acrobat shouldn't give you any trouble now.


                                                                    Should you face any issues with this, please post back.

                                                                      So... Here I am, back after another 30 day cycle! About 30 days ago I tried the deactivate/reactivate with assurances that I'd never see the problem again. Today I tried to open Acrobat X only to experience the exact same problem I had ~30 days ago.


                                                                      Amrita: Please stop assuring us that the problem is really fixed if it actually isn't!!


                                                                      Why are your legitimate, paying customers being punished by the methods you're using to stop software piracy?!? As a legitimate customer, I don't appreciate being punished for the crimes of others.


                                                                      I used the deactivate/reactivate fix again today. For the moment, it's working again. But at this point I have ZERO confidence that I won't need to repeat this process in another 30 days.


                                                                      Please get this problem fixed. Don't make me come back in another 30 days.

                                                                        • 73. Re: Acrobat X Wont Start

                                                                          Will Adobe's solution address Creative Cloud subscribers as well? I'm experiencing the issue, but the "deactivate a separate product" solution is completely ineffective (and the cache.db fix, given to me by Adobe support, only fixed the problem for about 2 hours).

                                                                          • 74. Re: Acrobat X Wont Start

                                                                            Hello dethousand,

                                                                            The acrobat not launching after 30 days is specific to the users who serialized their suite using a perpetual serial number at install time. It is not related to subscription users.

                                                                            So the workaround is for perpetual users. Can we have a connect session to look at your issue. I will send you a private message asking for your timezone and sharing  adobe email.

                                                                            • 75. Re: Acrobat X Wont Start

                                                                              I followed the steps stated in 46. mattlok1010's transcript, which is similar to the "correct" answer here. And it worked for a little while then stoped working again when I went to open another PDF.


                                                                              I re-read the answer and discovered:


                                                                              In case you still face a problem , try relaunching the other CS6 app once more and then launch Acrobat.


                                                                              This was an essential step for me as it completed the registration. As soon as I opened Photoshop, it came up with a bubble "registration complete" and Acrobat is working again.

                                                                              • 76. Re: Acrobat X Wont Start

                                                                                Please do not delte the cache.db. That step will only complicate your problems. If ypou have renamed it...please restore it back and follow the steps that I have posted in the workaround.... I assume you have done that.

                                                                                • 77. Re: Acrobat X Wont Start

Unfortunately this is my second issue with the Creative Suite (the first was with Dreamweaver), and this isn't cheap software. CS5 was phenomenal, but I'm very disappointed with the quality of CS6. Hopefully I don't have to come back in 30 days and go off the deep end..... stay posted
