I have tried everything except the right thing. I get this error message after upgrading to Windows 10 Pro v1803 when trying to start the app WordFinder (WFL in WFL.DAT). The file WFL.DAT exists on my computer in, most likely, the right places. (The app worked fine in Win 7.)
I have to be rather general: what do I need to do? I cannot even find privacy settings for individual users (only me at the moment, with Admin priviledges) or for individual applications (like WordFinder).
Thanks for your help.
