Hi Konstantinos, your lab config registry edit worked great on 11 install with only TPM 1.2, Thank you so much. On another without any TPM I used
HKEY_LOCAL_MACHINE\SYSTEM\Setup\MoSetup.Create a new DWORD (32-bit) Value named AllowUpgradesWithUnsupportedTPMOrCPU. Set its value to 1. This works too.
