I've tried repeately removing a program key from Local Machine, Software.
Using RegEdit, as Admin with all permissions (including "Full Control), I
keep getting the following error msg: "Cannot delete Acronis: Error while
Deleting Key." I exported the entire Software section and edited out the key
in Notepad and imported it back, but the old key (and subkey) is still there.
All other keys/subkeys, and related elements, of the program were
successfully removed. Thanks for your suggestions!
