I am having the same issues. The problem was that I did not close down all the browser windows in IE and Firefox, before I started to install the Reader. Uninstall the Reader first, then make sure no browsers are open and reinstall the Reader. It should do the job.
I finally got PDFs to work in my browser by doing the following.
1. Uninstalling Reader version 9
2. Installing Reader version 8.1 from the abobe.com website
3. I then had to uninstall via control panel add remove programs the adobe.com program, and I also uninstalled the Adobe AIR program.
4. I then checked in my Add Remove programs list and Adobe Reader 9 is still listed, I uninstall it again (why I don't know).
5. I then view a PDF file outside of Internet Explorer and I have to accept the license agreement in a popup window to get Reader 8 working properly.
6. I then go to a web page that links to a PDF file and finally I can view PDfs in the browser again.
We have around 30 PCs in our department with Adobe Reader 9 and some of them work in a browser and some of them do not, so there appears to be a conflict of some sort.
For info, I have Acrobat Professional 8.1 on my PC also.
As for the "Registering" trick mentioned by #32, how do you register it? Maybe I don't see if because I used the Customization Wizard 9 and deployed it via GPO. It would be nice to know the registry key for this then I could deploy that across my network.
I am experiencing a problem with Adobe Reader 9 when trying to view PDF files from within the browser. It causes an error which causes Internet Explorer 6 to crash. Application log shows that problem is with Acrord32.dll module.
Adobe Reader 9 will work is preferences are edited to avoid viewing in browser.
I was having a similar problem to this. If you updated straight from Adobe Reader 8, then this is probably the cause. I had to uninstall Adobe Reader 8 completely and then do a fresh install of Adobe Reader 9. Hope this helps.
I have the same problem as post 35. I know that the solution is to register Adobe 9, and then you can open PDFs via your browser. But I need to deploy Adobe 9 to 150+ computers and cannot visit each one and do this manually. Is there a way to bulk register Adobe 9 for 150+ computers?
Checking and installing the available updates after installing version 9 worked for me. I have Windows XP Media Edition with IE7. If you have unticked "display in browser" within reader 9 preferences to get it working as suggested in previous forum messages, make sure you re-tick it, otherwise it will still not load a PDF file within the IE7 browser window.
New Adobe Acrobat 9 prevents web browser from opening and displaying he content dut returns the "done" message from the browser activity bar. I am running the latest version of fire fox for yahoo as my browser, and once I uninstalled 7.0.9 vers for 9.0 version I cannot get the browser to display content,
Any one know what can be done to resolve this issue???
We got this error, when with customization wizard set "display PDF in browser" -> disabled and user is activating open PDF inside browser mode. All cases with enabled settings and "disable and lock" seems to be OK.
For those of you who followed Kuba's instructions regarding creating a registry key and found it didn't work, make sure the path in the registry key matches the path to where you have Reader9 installed.
I am using IE 7 and had downloaded Reader 9.0, but was unable to get it to work on the Web despite trying the suggestions I found here. I finally gave up, uninstalled 9.0, dowloaded 8.1.2, set it to not open a .pdf in a web browser window, and now I'm rolling.
John Peter, would you care to explain to me what the advantage is of
having a PDF (or a Word doc or...) opening in the browser and not in
the program associated with it?
Secondly, what difference does it make to a website what settings I
have in my Reader? I tried a couple of PDF links from the page you
referred to, and they opened in Reader 9 as expected. What happens
when you try?
The advantage of opening pdf's in the browser is that all our internal users are used to pdf's opening in the browser. If I change it to open in Reader they all start asking questions.
When I try to open a pdf file from the referred site "http://www.nza.nl/aanbieder/GGZ/12364" Adobe Reader opens and gives the error: "An error occured opening the document. Cannot find the file." This is with Windows XP SP2, IE6 and Reader 9.
I solved the issue now by opening op DNS to internet for the internal network, but why Adobe changed the way it handles PDF files in IE I don't know...
I had the VERY frustrating issue of not being able to open a PDF in a browser window after installing Acrobat Reader 9. Looks like the problem was rooted in the fact that I had a browser open when installing Acrobat Reader 9, which seems to confuse things.
Solution (as above):
Uninstall Acrobat Reader. Make sure all browsers are closed, then re-install.
Suggestion for Adobe: if you need us to close all browser windows when installing your software, then make us do so! It took me nearly two hours of my workday to fix this issue!
Ever since I've upgraded to Adobe Reader 9, I cannot open adobe files via the web browser. I need to be able to see my pay stub located through IPAY. An error or an alert keeps telling me that I cannot see the file without Adode 8 or 9. I had 5 and downloaded 9. So what could the problem be?? Please help!!!!
We rolled out Adobe Reader 9 using Microsoft's System Center Essentials. Some, but not all users had this problem after the rollout. We were able to fix it by opening Adobe Reader 9 and clicking Help--> Repair Adobe Reader Installation. This fixed most everyone's installation. However, I still have a couple of users who can't open PDF's in FireFox... Go figure.
Kuba- Is there any chance that you could explain how to correct this with the custmization wizard. I used your reg hack and it worked like a charm! I am just trying to determine how to fix my SI/GPO package. Thanks!
