Which ODCL Version are you using ?

Did it work correctly in earlier versions ?

I test it on my notebook:

My AutoCAD Version:AutoCAd 2007 and AutoCAd 2010

OpenDCL version:OpenDCL.Studio.ENU.6.0.0.13.msi

Can't work.

When i test on another workstation:
OpenDCL version:OpenDCL.Studio.ENU.6.0.0.13.msi
AutoCAD 2007 work fine. I change nothing,why?
