I'm currently running Design Suite MEP 2012 and I don't have the option to use "express tools" in AutoCAD MEP. I did go to start and remove programs and try to add that feature and it prompted me thru a series of things. The last step is to insert disc but MEP suite comes on a Flash drive and I don't get the option to navigate thru that. Any suggestions? I really need the express tools and I'm sure its something pretty basic but I cant figure it out . Thanks
