Hi, I am finally getting used to the way solidworks, works(doesn't work!!) lol I now face a new challenge of installing 2004 gulp! Here is my setup at the moment:- 1 Novell 5.0 server and 23 mixed windows workstations. 2 windows workgroups. Solidworks 2003 on 1 XP pro machine on workgroup 2. Pdmworks and the toolbox are on another XP pro machine with mirrored scsi hard drives, (this machine is used as a drawings server which is backed up every night onto a built in scsi tape drive), but is still only a work station! this is also on workgroup2. There is also another XP pro workstation on workgroup2. We are hoping to get a windows small business server 2003 soon, he! he! and pigs might fly! But that is what the god like creatures above have said. (Soon means within the next 5 years going by their past record!) Ok, now, will I have any problems upgrading to 2004?? huge question, I know, but one I need to ask. Will my Toolbox be over written etc... blah blah ? Thanks
