Recently updated my desktop to a new Windows 11 machine. When I try yo install CADHobby using installation disc, I get a message that says "There was a problem starting C:\\Windows\Installer\MSI74D9.tmp. C:\Windows\Installer\MSI74D9.tmp is not a valid Win32 application. I'm completely puzzled what to do next. Had no issues installing it on my old Win10 machine.
