That's what I don't get Henrik. My old gamer was Win 7 64-bit, I would assume Win 10 64-bit would be the same. I guess not.

Opened X86 DOS window, manually did same commands as the INSTALL.BAT that came along with PBP v2.46 CD and it doesn't decompress as expected.

Even set PBP246.EXE to run as ADMIN, tried both Win7 and Win XP sp2.
