format it, install linux and tell your boss to not ask again for an employee to help on a particular issue, games in special

Backing to reality,
- did u tried thu game' uninstall option or thur add/remove programs? try both
- if not works, remove directory and registry entries. On registry look for game' manufacturers keys...

i hope you have all media do reinstall it (or you boss had d/l from e-mule? )
