I’ve got the same problem and the problem is due to Software AG use of the old install package. It will check if the system has any ‘unfinished’ business before allowing to install.
I’ll guess you will encounter the same problem with other vendors using this install program.
Here’s how I solved it.
Open the registry but invoking regedit in the ‘run’ menu.
Before taking the actions below remeber to export the registry or parts of it. Just in case…
Locate the following registry key:
Delete any PendingFileRenameOperations values in this key. Or delete the entry completely
You may also need to check for and remove pending file rename operations in the following registry keys:
NOTE : If the problem is still not resolved, check for the existence of old installation files in your TEMP or TMP folders, check for the existence of a folder named “$!$!$!$!” in the root folder, or try emptying the Temporary Internet Files folder.
To Delete Temporary Files
Antivirus and printer drivers can also cause the problem (Lexmark have been a problem). You can solve this by temporarily disabling antivirus and/or unstalling the printer drivers.
