I posted this on other sites, but thought I may get some help here, too... :
We had to uninstall our MV and AutoCAD. After installing AutoCAD 2006, and attempt to upgrade to 2008 (something I've already done in the past), the CD drive doesn't recognize the disk. It acts like there is no information on it disk itself. I get the same result on a computer that already has 2008, but if I try the disk on any other computer it works fine. I have Windows XP SP2, with the usual amount of comp. specs that will run all the stuff fine.
I've already restarted and relogged on, to no avail. Also I've tried "refresh" when viewing the D: drive in windows explorer. Any ideas on how I can get this thing installed? Thanks again!
