Go to your Scorched3D program folder (usually C:Program FilesScorched3D) and rename or delete the OpenGL32.dll file. It is incompatible with anything other than XP or Windows Server 2003.
You will also need to create a new shortcut pointing to C:Program FilesScorched3Dscorched.exe because the system will think the installation is corrupted and try to reinstall files if you use the standard menu shortcut.
Thinkpad T22 + Win2K Pro = no go (still) – system crashes.
Thinkpad T22 + Win98 is OK. I haven’t tried enabling TexSubimaging.
On Win98 with the “bad” installer, I got a weird message from the installer that it couldn’t install a registry key in UNKNOWNFeatures – this was safely ignorable. I still had to dump the OpenGL32.dll and recreate the menu shortcut.
