Don't leave the community though... I'm sorry about not showering yesterday - I realize not too many folks take kindly to the smell off Guadalcanal too well... too much coffee and pizza to have time to do that, but I promise I'll clean-up today! But in all seriousness, have you tried changing the Property settings on the SH4.exe file? I never had a worry in the world with SH4, neither Steam, UPlay (UConnect now) nor disk. They all ran, and they all take mods just fine... until the "New!!!" Windows 10 came along the other day... I now have to have different settings on the SH4.exe for each of the 3 computers, and had to experiment with all three to get the game to run. My Windows 7 machine does fine, but all 3 Windows 10 machines had to be changed. Here's a post with a picture I did yesterday in billkunert's
SH4 won't start after recent Win10 update post. Experimentation is mandatory in today's 'modern' computer world when you are dealing with antiquated "legacy" apps from the Windows XP (DirectX v9.0c) days, unfortunately. The game is a blast though still -at least for me it is - after how ever many years it has been since the SSI SH4 (v1) came out...
