Is it possible to run Steam games that reside on my Mac OS X partition from my Windows partition?

I'm using Boot Camp to run Windows 7 on my MacBook Pro. I'd like to play Windows only games but my Windows install only has 20GB of space.

I installed Steam and my Steam games on my Mac OSX drive using MacDrive. When I try to run any game it says that it can't run SteamService.exe.

I have no idea what's causing this. Any help?

SteamService.exe is the name of the Windows Service executable, that Steam is trying to launch.

All Windows service executables must reside on an NTFS formatted partition, or else they should be run with elevated rights ("run as administrator" option).

Steam can have problems with Windows 7 and certain antivirus programs. I would recommend turning off your antivirus program and running either of these commands from the administrator command prompt.

C:\Program Files\Steam\bin\Steamservice.exe /Install "C:\Program Files\Steam\bin\SteamService.exe" /repair <--Make sure to include the quotation marks.

(If you have Steam installed on another path, you need to replace C:\Program Files (x86)\Steam with the correct path. Also, 64-bit systems will use Program Files (x86) instead of Program Files.)
