Be aware that Express 6.19.2 needs .NET Framework 4.7.2. My Windows 10 PC is stuck on an old version in order to stop perpetual failed attempts to upgrade Windows 10. Therefore, I have turned the Windows 10 upgrade feature off.
In trying to upgrade to Express 6.19.2, my PC seems stuck in an endless loop because it's trying to install .NET. I may have fubared Express and maybe my PC. Fortunately, I do have an image backup.
I've cancelled the .NET install and it seems to have rolled back successfully however I may not be so lucky with Express. Somehow, I am going to have to find 6.18 and perhaps stop it from ever upgrading again.
