Hi! there, I have installed and uninstalled a version of Nero 6.6 OEM Suite on my system on several occasions. I am running Windows XP Professional. However on this occasion, althouigh I am attempting to install it on the same system as before, every time the installation gets to 33% the following message stops the installation: (Trouble in installing Nero CD2K Check Tool). I have tried to install it with both the firewall and the antivirus turned off, I have completely uininstalled Nero several times, but I cannot find any way to correct this error. Any advice would be very much appreciated. Thanks to all who take the time to reply.
