Which OS are you working on?
Internet explorer 8, and Firefox 4.0. I get the same error on both.
I asked for OS like Windows XP or VISTA or Win 7? Do you have any folder redirection in your PC?
Windows XP, no folder redirection that I know of.
Can you check if all registry entries here pointing corrct location
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\ Shell Folders
If not then correct these entries and then try install of Reader X.
Else you can try install of Reader X by login into PC as some other user.
I have found out that I cannot upgrade to Internet Explorer 9 unless I buy
and install Windows 7. Microsoft can whistle Dixie before I do that. I have
to replace my computer soon. Perhaps someone will come up with something
better that the MS Windows kludge by then.
I am not going to waste my time with the Adobe reader problem any longer.
Let Adobe fix it. I'll check back with them in a year or two.
I had a very similar problem which was being caused by me being unable to uninstall Adobe Reader 8 on a clients machine because it was installed from a drive that no longer existed.
My solution in the end was pretty simple.
Take a CMD prompt - Start \ Run \ CMD - Enter
Now in the cmd box type "subst f: c:\" - Enter. This command will create a virtual (temporary) drive that just points straight back to your c:
Now that your computer thinks it has a F: - go ahead and install the new adove version.
(I also had to kill a search process but I think that is another unrelated problem - let me know if you get this error).
Once it has installed a reboot should remove the F: but if it doesn't, take another command prompt and type "subst f: /d" - This removes the virtual drive.
I've just started my own company so I hope this works for you and feel free to pass on a plug for my company - www.sureit.co.za
I wish that Adobe would fix this problem! It has been an outstanding issue for several years.
I have my "My Documents" folder on a network attached drive. So, the two registry entries above point to an external drive (e.g. U:\John\My Documents).
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Personal --> U:\John\My Documents
HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Personal --> U:\John\My Documents
I changed the "U:\" to "C:\" and I was able to install my update. Interestingly, whiel the C:\ drive is valid, the directory "C:\John\My Documents" doesn't exist.
