SFX 7z extension install error. ( PBextSetup64 )

In Windows 11 the shell extension (32/64) cannot install because of an error.

Paquet Builder 2021 (64) trial V. is installed at default location.

Thanks for the report. The Shell Extension was not updated to work with PB 64-bit. It’s on our TODO list for PB 2023.
