I recently reinstalled SW. The procedure is to make sure youback up the vault before you start unistalling and downloadingsoftwre. For a change I did the right thing and did this. After thenew software was installed, ( A lot of water went under the bridgebefore this including winding all my files back to a previous datethrough Wiindows XP.) When I accessed the Vault I noticed that someof the files had gone missing including some that I'd just beenworking on and submitted to a client. After a few minutes of handwringing and teeth grinding I remembered that I'd backed up thevault. To reinstall the vault, you stop the vault service, renamethe backup vault and current vault folders and restart the service.It really was that simple. I was greatly relieved to find the filesback again.SolidworksWorkgroup Pdm
