Hello Carl,
Thank you for your reply. With your information I tried a few things & ended up installing on my USB external drive; not my preferred choice, as I now have 3 locations with programs, but it works. I didn't have to have an empty drive, but it's where I prefer to keep most data files. The drive that TTax didn't like was my SD card, where I install most programs. Strange that it would easily accept an external USB but not an SD card in a slot. Obviously, something in the program that I can't change. The program is a bit slower this way But it's tolerable.
When you said I wouldn't be able to access other programs on the preferred drive while TT was running I knew that would be a problem; my anti-malware is there.
I'm fairly computer literate but have never mapped a drive for anything other than keeping the drive letter, so I'm glad I asked.
Thanks & All my best,
Denise
