OK, similar question, but with a curve.  I have a desktop running Windows 7 Pro.  I'm trying to install my old version of QB 10Pro.  It won't execute because the message says a third-party support program isn't working.  The third-party program, my guess, is Flash Player 10, which Adobe disengaged on January 21, 2021, as an EOL program.  How do I get your QB10 Pro to install on my Windows 7 if the third-party (Adobe) won't let me install Flash Player 10?
