Is Acrobat X installed as a part of a CS6 Suite or stand-alone?
If it's part of a suite, please check out: http://helpx.adobe.com/creative-suite/kb/acrobat-failed-launch-30-days .html
If it's a stand-alone: Are you receiving any error message? Has it ever worked? Any ideas on what's changed?
It's a stand-alone. It gives no error messages, and it has worked (I don't know how long ago.) The only change made to my system is transferring photographs from a CF card to my external hard drive, which is not a new occurance. I have tried opening Acrobat X with the desk top icon, and the start menu - nothing happens: but when I right-click on the start menu, I get the regular drop-down window that includes "Unregister product." Again nothing. I also have Adobe CS6, Lightroom 4.1, and PSElements 10 on my system. Thanks for your help.
Could you try the steps outlined in that document I referenced previously? You say you have CS6. Odd as it sounds, there might be some serialization issue going on here with your stand-alone installation. Even if it doesn't affect your Acrobat installation, deactivating/re-activing Photoshop won't hurt.
If that doesn't resolve your issue, a few questions:
Greetings and felicitations David
Thanks for staying w/ me on this, and I'm sorry it's taken so long to respond. I have tried all the steps - still nothing. I'm running
Windows 7 64-bit, and am current w/ the updates. I'm ready to throw the program into the trash. I had similar problems w/ Elements 7. It just stopped working, so I had to upgrade to Elements 10 for the wife, and PS6 and LR4 for me. I like Adobe, but the programs can be cantankerous.
Again, thank you.
The solution to your problem could be recreating the adobepcd/cache file as it contains the licensing info for all your adobe softwares,and it seems to me like once we recreate it your problem will be fixed
Now before you recreate it let me tell you that it will remove the licensing info for all the adobe software and you have to reenter the serial number for all the adobe application (i.e Adobe CS6, Lightroom 4.1,Acrobat X and PSElements 10) so make sure that you have all the serial numbers with you before you try it
The location for Adobe PCD/Cache is
C/Program Files/Common Files/Adobe/Adobe PCD
so you can move this file to other location however do not delete it so that in case we require it we can restore it again
and hopefully this should resolve your issue
I just checked and I do not have Adobe PCD on my system. I'm going to delete it, absorb the loss, and try to find an open-source version. I truly appreciate your help on this problem, but it is now beyond my "ticked off" point.
Again, David, thanks.
