I noticed that my installation of Adobe Reader 9.4.5 was asking to upgrade itself and when ever i clicked ok on the upgrade option i keep getting an error 1327 Invalid drive k:\ message. My machine does not have a K drive. I tried uninstalling the reader and it came up with the same error. I ran the windows installer cleanup utility and tried to remove reader. It seemed to work, but when i try to install the latest version of reader, i get the same error message. Now i dont have any version of reader that works on my machine and i cannot get it to install. Any ideas? How do i manually uninstall reader? Thanks.
Can you please check the value of the registry entries at the following location:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders
In case the values for any of the entries (i.e. Common AppData, Common Desktop, Common Documents etc.) is referencing to K:\, change the value back to look something like below and you should be good to go.
Hope this helps
