I've tried the manual install. It did not work. Actually I tried 4 methods (not just the 3 listed above):

I have an M93p SFF Thinkcentre, which is restricted from updating to Windows 11 merely due to the version of TPM installed - tpm.msc tells me I have version 1.2.

all other specs exceeds the required for windows 11 except for TPM issues.

It's the same I have here, but mine works. I'm asking author of ChargeThreshold.exe what could cause your problem and how to debug it. Please wait.
