Dave had a problem with a Windows update and he realized that if he deleted another program that Roxio installed, then it worked just fine. But now several programs he relies upon don't work. Leo says that it could be a problem with apps that are 32-bit, though Windows 10 still supports them. Microsoft may have killed off third-party 32-bit support. There is a program compatibility troubleshooter in Windows 10 Control Panel. It could walk him through how to run his app in compatibility mode.
