Adobe Acrobat 8 Pro stops responding

Adobe Acrobat 8 Pro stops responding as soon as anything in the PDF window is selected.
There was a patch to upgrade to version 8.1 which said it included support for Vista so i downloaded the patch and installed it. Updated it to most recent version of 8, experienced same problem. When tried to uninstall it, the uninstall hung and i had to do a manual uninstall.
Researched a solution on some message boards and did the following steps:

1. Follow all the steps to download SubInAcl - 

2. Open up Notepad (in accessories in the start menu)

3. Copy/Paste this code into Notepad, and replace the parts that say "YOURUSERNAME" with your actual user name:

cd /d "%programfiles%\Windows Resource Kits\Tools"

subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f /grant=restricted=r /grant=YOURUSERNAME=f /grant=restricted=r /setowner=administrators
subinacl /keyreg HKEY_CURRENT_USER /grant=administrators=f /grant=system=f /grant=restricted=r /grant=YOURUSERNAME=f /grant=restricted=r /setowner=administrators

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f /grant=users=r /grant=everyone=r /setowner=administrators
subinacl /keyreg HKEY_LOCAL_MACHINE /grant=administrators=f /grant=system=f /grant=users=r /grant=everyone=r /setowner=administrators

subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f /grant=users=r /setowner=administrators
subinacl /keyreg HKEY_CLASSES_ROOT /grant=administrators=f /grant=system=f /grant=users=r /setowner=administrators

4. Click File>Save As and save the document as registryfix.bat. Save the file to the folder that contains the SubInAcl program that you just installed.

5. Open that folder and click on the file, and the file will run. Let the file run completely until the window shuts itself. DO NOT end the process early.

6. Restart

This resolved the issue temporarily, but shortly after it started happening again and hasn't stopped since. This looks to be a Vista problem. Adobe Reader 9 is installed on the pc, and that works fine. Computer is a brand new HP notebook running Vista (32bit OS) Home Premium Edition with SP1. I would just like to get Adobe ACrobat 8 Pro installed and working. I appreciate any suggestions. Thanks in advance

This sounds like there is something strange about your permission settings. I am also not convinced that you should have 9 reader on the same system. It used to be a 'no-no' and Adobe never been keen on this, and with what they now calling the self healing registry I still question whether it does not create problems...

Have a look at:

I would suggest uninstalling both using the manual procedure after uninstall for A8 from Control Panel and then reinstalling the Acrobat Pro version and patch using the 'Run as Administrator' shell option when right-clicking the exe file.

To remove A8P manually:

To remove r9 use the Control Panel option.

Thanks for the suggestion. My client who is having the problem has been busy lately, but i'll try my best to implement your suggestion tomorrow. I'll let you know how it goes.

I tried everything you suggested verbatim, however the issue persists. Adobe 8 Pro starts, but as soon as anything in the Adobe interface is selected, it immediately stops responding.
The 7 Worst Nightmares of a Sysadmin

Fear not! To defend your business’ IT systems we’re going to shine a light on the seven most sinister terrors that haunt sysadmins. That way you can be sure there’s nothing in your stack waiting to go bump in the night.

If you run a full uninstall and registry clean and then reinstall the latest update with Administrator account privileges to create a clean install it is unlikely that it is caused by an Adobe error.

The only other thing I can think of is the DEP settings. You could give the following a try:

Other than that I could only think of a hardware fault such as a memory issue.

Sorry my ideas are getting slimmer.

one more thing. Adobe launches the Updater shortly after the launch of the application. It could be coincidental to the symptoms you describe, but if for whatever reason that gets interrupted or blocked it may react similarly...

Normally you expect the firewall or security app to throw a warning but maybe this happens silently and Adobe just hangs.

It is worth disabling any software firewall, AV or Internet security app momentarily to do a test of Adobe.

I did a manual uninstall, then made sure the firewall (Windows firewall, no others exist on his pc) and all security apps were disabled along with their services (AVG and Windows defender). Also, DEP is turned off, and while all of that was set i did a clean install of Adobe 8 Pro under the admin account. Upon completion, the same problem persists. I am at a loss here, i'm thinking this version simply won't work with his computer (assuming version 9.x will?)
Any other idea's? :)
Not that I can think of at the moment...unles there is something odd with the system fonts...

I would strongly assume 9 will, unless there is some hardware issue.

Baffled is the word

Yes, i agree that trying 9 would be a good idea. I'll install a trial version of 9 on his pc and see if that works.

I manually removed Adobe Acrobat Pro 8 again then installed a 30 day trial version of Adobe Acrobat Pro 9, and it works fine. I don't know what it is, but something with version 8 just won't work on that pc.
There may be some strange things going on with 8 in your registry, it alledgedly came with an 'auto-heal' function which caused more problems than it cured.

I guess one could try forever, short of a clean install after format.
