Windows 10 no longer supports 32 bit programs and in most cases won't allow them to be installed. If a program is already install like my ACDSee V12, it may continue to work but may be wonky. In my case ACDSee would work but it took 10 seconds for it to load. When I tried an uninstall and re-install, the setup program would just fail with no explanation. Going to standard version 2018 solved the problem.
