The Witcher orig.

[nando2002]

According to the forum:
"The Witcher protection system does not support any kind of emulation software such as e.g. CloneCD or DaemonTools. Using it may result in non-detecting a dvd with the game. Also try downloading drivers for Tages from http://www.tagesprotection.com/5.5.htm Unistall older drivers, start The Witcher and allow Tages to install newer ones."
If you have DT or similar, remove it and try.
I Don't see people complaining with loading or install problems. Point me the forum thread so I can help you.

I've updated tages numerous times with no success, and removed both DT and Alcohol, i've even went into the registry to remove every key left by those programs, with no success. Here are some topics from the official forums:
