Is there a way to point SW 2007 back to the originalinstallation source when it can't find it. I have the 2007 DVDcopied to my HD.I'm trying to update to SP3.1 from 3.0 and now theupdate can't locate the original installation source. I had noproblems with any other SP until now.If I try browsing to thesource file it's looking for, the file is where it was originally.If I try to point it to the DVD I get the same error message thatthe installation source can't be found. I could see if I'veinstalled it from a different source but have always copied it tothe HD and installed from there. No disk swapping that way.SolidworksAdministration
