Open Autocad 2011 win7

[Anonymous]

Hello


I have been developing a vb.net application with autocad 2010 and windows Vista, till now the application is working perfectly but when I try to develop the same application in Windows 7 (64bits) and Autocad 2011 (64bits) the application gets an error in the following line



 Dim m_acadappl As New Autodesk.AutoCAD.Interop.AcadApplication



ERROR

Creating an instance of the COM component with CLSID {6D7AE628-FF41-4CD3-91DD-34825BB1A251} from the IClassFactory failed due to the following error: 80010001.


I really appreciate if Someone could give me an orientation on what may I do to solve it, since is very strange that is fully working in one version and on the other one no.

As you made a point of mentioning 64-bit, I'm guessing this is the first time you tested with AutoCAD 64-bit and your application is referencing the 32-bit AutoCAD Type Libraries. You need to either rebuild with the 64-bit TLBs, or rewrite your application to use late binding. (The TLBs have different GUIDs between 32- and 64-bit.

Sorry if you already knew that and that isn't the issue.
