I already have SH1, SH2, SH3, SH4, and SH5 all on original discs and SH4 U-BOAT as a digital download all work great on this win 10 pc except SH4+U-BOAT which has the mentioned activation problem after working for over 2 years on it. If I buy the steam version with U-BOAT missions is it easy to install duplicate installations on my other hard drives?
