Hello Community,

We upgraded from windows 7 pro to windows 10 pro last Friday.  Everything went well.  Ran QB Desktop Premier Contractors Edition 2018 all weekend.  No issues.  Sent the system back to the office this morning, after booting, QB will not open.  The splash screen comes up and then it just goes away.  This is the main computer that houses the QB database that is used in a multi user environment on a peer to peer network.  I can open QB from another computer just fine so it isn't the database.  Looking at the event viewer, right after boot up MSInstaller ran several times.  There is then a .net runtime error

Application: qbw32.exe

I have uninstalled everything I could find that installed this morning but no joy.  Windows 10 Pro version 2004 build 19041.264.   Does anyone know how to fix this?  This is becoming a crisis as we need to be able to access QB on this computer.

Thanks for your help
