I am using IV2010. A while back Mark Flayler replied to a problem and it told me a site to down load sheetmetal extent source file to get the gauge of the sheetmetal to appear in my parts list. I was running xp 64 for a long time and program worked great. now i got a new computer with windows 7 and the program doesn't seen to work any more. Has any one elese used this program with windows 7, can somenoe tell me how to fix the problem, or if their is another way to get the gauge to show up in the parts list i would like to here that as well.
