Anytime I try to execute 3d orbit, I get an unhandled exception pop-up error box (acrros the blue at the top of this box it says
"Exception in C:\Program Files\DWG TrueView 2009\acmvtools.arx ARX Command". And the program has to be aborted. I also get the same error if I attempt to open a dwg that was last saved in a 3d view -- that is, opening the file fails with the aformentioned error and the program must be aborted.

I am guessing it is a similar problem as the below. This error is in DWG TrueView 2009. I have this installed (the latest true view). The AutoCAD verion I am using is 2008. I do see "acge17.dll" in "C:\Program Files\DWG TrueView 2009" dated 02/09/2008. I also see another ""acge17.dll" in "C:\Program Files\AutoCAD 2008" which is dated 02/12/2007.

If this is a conflict, how can I get the dwg trueview 2009 3dorbit to work? We have shared AutoCAD 2008 licenses. If they run out and we need to look at something we want to use the trueview. (windowx xp)
