Getting "Browser not supported" error when trying to register my QBPro 2016 on a new PC

Hi,

I am retiring my old PC and have installed QBPro 2016 on a new PC. After a successful install, I am getting error "Browser not supported" on my new PC with Windows 11 Pro when I try to activate/register my QB.

I have tried updated both Google Chrome and Microsoft edge without success. I'll appreciate your help in resolving this issue. Thanks

John
