try to delete the registry keys related to valve / sierra / CS in ur registry using regedit
or use a gud registry cleaner like RegClean
It shud help
btw.......which exe is not found??
the exe which starts the game of course
maybe the cd has gone currupt then...
no man, the CD when inserted will (autorun) try to RUN the game, & when there's no GAME folder (& its .exe), then its usual that it'll show that error.
@techgeek , follow the instructions of @stalker.
& you can also goto the Control Panel, Add-Remove Programs & try to Delete its entry. (just click unistall in add-remove progs., & windows will say its a invalid entry & delete it)
Thanks for the help its working properly now. After the autorun just press "RE Install"
