I was puzzeled that myPC did not meet the requirements.
(AMD 1700X, MSI Mortar B450, RTX 2060, 16 GB, plenty ssd space and TPM enabled )
Turns out that some CPU's are not supported.
Here's a link to supported AMD cpu's. https://docs.microsoft.com/en-us/windows-hardware/design/minimum/supported/windows-11-supported-amd-processors
Some sources says that Windows 11 might support more cpu's later...
I will keep on trying. Best of luck to everyone! :-)
