Hello: While trying to create a new drawing file, pasting in an existing assembly, the following lethal error is displayed on Inventor 5: "INVENTOR caused an exception 10H in module MSVCRT.DLL at 0187:7802be4b." I have seen one reference to this error in the archive but no suggested resolution. Any help would be greatly appreciated. I am currently running a PIII 550 with 512MB SDRAM and 13GB HD, ATI Rage Pro 128 Graphics card. Woody
