We've been having the same issue, but on 3 out of 5 machines. Our office is using Intel Xeon based machines running Win XP Pro. All copies have been working solid for months but two weeks ago one by one, VWks 11.5 crashed/disappeared when the menu was clicked.
Tried uninstalling but was unable to do so. It supposedly got rid of the 11.5.1 patch only and now we can't uninstall through the add/remove programs control panel. Has anyone successfully wiped VectorWorks 11/11.5 off their machines?
Got a VectorWorks 11.5.1 full install disc through our sales rep. Installed the full version over the existing one but it didn't fix the problem.
Deleted our custom workspace through windows explorer, but it didn't fix the problem.
As for virus scan apps, one out of the three is running Norton, the other two are running McAfee.
The problem lies somewhere within the User files/prefs. The crash seems to only happen within one local account on each system. Once logged on as the Administrator of the machine, there is no crash. Same results logging on as a guest - works fine without crashing.
Been scouring the Documents and Settings folder for any Nemetschek or VectorWorks based files or folders to delete, but have not found a one.
Any ideas?
