Thank you for your quick reply, I think I'm going to wait a few months with the roll-out to 2008. This has too much impact on all the users. AutoDesk should find a way to make upgrading easier, we have about 10 designers and 100+ consumers. In this case we have to un-install the server and un-install vault 5 / re-install the vault 2008 on 100+ PC's, and all this in an acceptable time frame. It would already help a lot, if Vault 2008 can now be installed any pc, without having to install AutoCAD first.
