Beavis & Butthead Do U. for 64Bit Windows:

Due to the installer the game uses being 16bit, the game cannot be installed normally, and instead you must do things manually.

Copy the folder “Beavis” to C:\Program Files (x86)\
Modify “AppPaths64.reg” “CD-ROM Path=” to the drive letter of your physical drive if you burnt to Disc / Own the real thing / Virtual CD Drive
aftre doing the Above, run and add to your registry all 3 .reg files.

This has been tested with Windows 7, not 8.1 or 10 and you may need to set Compatability to windows 7 to as far back as Windows 98  on Beavis.exe
