I have Just tried to install solidworks 2004, but I had a few problems. The installation could not find the helpfiles0.cab on cd1,even through I could, this was after trying 2 machines with 3 cdrom drives. Copying cd1 to the hard drive and installing from there, cured this problem, but gave me another, how to install cd2! Ha!, by copying the files from cd2 to the same folder, allowed the installation to work, then doing the same for cd3, allowed a complete install. 22 year of IT experience, has served me well, there is always a way! There is only one problem, I can't get around, and that is it will accept my serial number, but not my registration code! Hmmm...one phone call to my VAR, I think. I have only fooled around in 2004 for about 30 mins, but I must say, wow!, it's looks and feels really great. My only hope is, that they get around to doing the same great job on PDMWorks! I like to give credit, where credit is due, Solidworks 2004 a big yes, PDMWorks no. I have another great job tomorrow, upgrading a drawing server with bigger hard drives and a new raid card, to be able to continue to use Solidworks, it has filled the old hard drives up!
