    Sources files are not used by a clean install, except: install.wim/esd, boot.wim. lang.ini, setup.exe and the pid.txt or ei.cfg.

    Hehe of course I used "Win 11 Boot and Upgrade FiX KiT v1.5" ='D

    But Id like to dig deeper a bit. I want to know more about appraiserres.dll and everythign it is involved into.
    Also, where would be the origin of the idea replacing it ? I found other sites that claim such trick was used before and that using a newer appraiserres.dll on this Windows 11 might work too.

    I bet you tested that already ?

    Didn't work for me, and what does it matter from which build you use the dll, as long as it works it's fine.

    Appraiserres.dll only need to be touched for inplace upgrade.
    Deleting it worked for me

    Well, appraiserres.dll is in the sources folder, so some source files must be used in a clean install. If deleting it also works as stated in the post above, is there another file that the install uses other than appraiserres.dll to check the system is suitable to install Windows 11 on?

    Anyway, the "putting the Windows 11 install.wim in a Windows 10 iso" trick worked for me on a Haswell CPU which didn't have TPM.

    appraiserres.dll fix does not help for installs from boot.

    These are the boot.wim index 2 fixes:
    Code:
    Dism /mount-wim /wimfile:"WORK\sources\boot.wim" /index:2 /mountdir:"%SystemDrive%\Mount_Temp"
    Reg.exe load HKLM\MDL_Test "%SystemDrive%\Mount_Temp"\windows\system32\config\SYSTEM
    Reg.exe add "HKLM\MDL_Test\Setup\LabConfig" /v "BypassTPMCheck" /t REG_DWORD /d "1" /f
    Reg.exe add "HKLM\MDL_Test\Setup\LabConfig" /v "BypassSecureBootCheck" /t REG_DWORD /d "1" /f
    Reg.exe add "HKLM\MDL_Test\Setup\LabConfig" /v "BypassRAMCheck" /t REG_DWORD /d "1" /f
    Reg.exe unload HKLM\MDL_Test
    DISM /Image:"%SystemDrive%\Mount_Temp" /Cleanup-Image /StartComponentCleanup /ResetBase
    DISM /Unmount-Image /MountDir:"%SystemDrive%\Mount_Temp" /Commit
