I don't find anything specific to the program, but the error message appears in a bunch of descriptions of errors fixed by various SPs SRs and updates.

What Operating System you are using might be helpful, and whether it is current with respect to available updates and patches. Win2K should be at SP4 at least, and WinXP at SP2. Earlier versions are unsupported, so there may not be much you can do about getting current.

The error message may imply that some of the information recorded when the program was installed has been corrupted, or a component of the program has been moved; and the uninstall just can't find something that's on the list to be removed.

You can look in the folder where the program was installed, and see if the program itself put an "uninstall.exe" there. Using Control Panel first is generally recommended, but if that doesn't work the program's own uninstall, if there is one, is the next step.

A "sometimes works" method, when nothing else works, is to reinstall the program, which will give the uninstall utility a new script with the right locations for all the parts and pieces.
