TT Deluxe 2021wont install from CD. I get an error - "A file that is required cannot be installed because the cabinet file Data1.cab has an invalid digital signature.

I have previous versions installed and they still work. The only fix I've seen is to uninstall and reinstall, but I haven't gotten it installed at all. Any suggestions?
