https://forums.autodesk.com/t5/autocad-forum/how-to-switch-user-without-reinstalling/m-p/5674016#M325856 <P>There shouldn't be anything special that needs to be done. Any user logs in and launches AutoCAD. The program installs available to all users. There should not be any errors. That is why it seems you have a greater issue going on. It sounds like something that maybe should be posted in the installation forum with a subject title along the lines of "Secondary users get errors when launching AutoCAD" or something to that effect. I think people may see the title of this thread and not fully realize what is happening.</P> <P>&nbsp;</P> Thu, 11 Jun 2015 18:13:13 GMT bryce.thelin 2015-06-11T18:13:13Z
