I had WinFax Basic, which came with my Compaq A900 all-in-one. I have been using it without any problem.
Recently, I had trouble installing Norton AntiVirus 4.0. The expert at Symantec told me to delete all files, folders, etc. referring to Symantec because I had a previous version 3.0. I did that and Norton installed okay.
However, in the process WFXUNIST.ISU which was in C:\Program Files\Symantec\Winfax also got deleted, and my fax does not work.
Now, when I try to reinstall WinFax Basic, I get the message to first "Uninstall WinFax Pro". When I try to uninstall WinFax Pro, I get the message "WFXUNIST.ISU" not found.
Since I never installed WinFax Pro (I had WinFax Basic) how do I resolve this problem?
