The exact message that I get is the same on all machines that will not take the service pack "Mastercam not found or not configured properly, upgrade not possible."

Are you referring to the full installation CD with SP2 already integrated? All the installations were done with Mcam v9.1 with no previous 9.0.

Using Mcam v9.1 why is it that on half of the machines I have attempted to apply SP2, it gives me an error that it is not configured properly or not installed. I have installed all previous patches and service packs, it just chooses to install on some machines and others it gives me errors. Is there anything I can do to get the service pack to apply itself??

I have recently installed Mastercam v7.2c on a new P4 2.0Ghz with 512 of pc2100 and an Asus GeForce 4 4200 Ti 64 MB Graphics Card. The program seems to slow down after about 15 to 20 minutes of operation and gets even worse when zooming in at a higher rate. I have installed all the latest drivers. This is the only Mastercam workstation that is running XP Professional and the only one that has a problem with Mastercam. Would like to know if anyone has had the same problem, Thank You.
