SST was never compiled to run under WindowsNT. 

The usual failure under Windows NT/2000/XP is that the gamer can get as far as loading the CD into the computer's tray (all this within the first room of the game) and then nothing else happens... the game does not proceed to the next stage but still allows simple actions to be performed (but not left/right turning of the character). This is not solvable for Windows NT.

SST can be run under Windows 2000 by installing it with a file named apcompat.exe found on the Windows 2000 Installation disc. This file has since been updated from Microsoft and is available by download from them (the Windows smart update process should find it). A number of games with the original apcompat.exe file reported that this did not work for them, but we think the updated file should sort that out now.

The following reports are all from gamers who have volunteered information on the subject, and we express our thanks here for their effort.

I have got STT to work under Windows 2000 
Here is how i did it. 
I just installed it as normal and when to play I run the apcompat.exe from the win2000 CD and chooses win95 and most important is to chose the setup.exe on the first disk of STT (not the st.exe in the installed files) and then press ok.
Then chose play STT on the menu. 

I have only tested this on my Dell Inspiron 8000 but it works every time.
I played thru the hole game doing this.

I've managed to get STT running on Win 2000 and I believe the same method will work for XP. You need to apply SP2 to Win 2000 and then logged in with administrator rights run
reegsvr32 %systemroot%\apppatch\slayerui.dll

You'll need to then right click the shortcut to the STT executable, select properties and then select the Compatibility Tab and choose Win95 compatibility. The only limitation I've found is that the whole game needs to be installed to the hard disk, otherwise it fails in loading overlay videoware from the DVD.

By downloading the updated file from this location htttp://www.microsoft.com/windows2000/downloads/tools/appcompat/default.asp
One can then make some changes in the option of the 'run file' in the start-menu.
Just change the comability mode to windows95 and it will work perfect.
