visual studio 2008
any help would be greatly appreciated

Hello all
I am trying to do exactly what  Late_nighter was trying to do, but with  vs2010, and get the same results.  In this post http://www.machsupport.com/forum/index.php/topic,11589.0.html
They are trying to do same thing. I have used regsvr32 to try to register  mach3.exe and i get the same error (not a valid com obj). 
It seems i can not find the "Mach4.Document" class in the window registory, like the second thread says to do. I see "M3plugin.Documents" and others using regedit. It also looks like no one has help these guys find the solution..
I am hoping some one can point me way to find a solution.  I am not a C++ programmer but can get around in C# OK. I would love to create some plugins for my home shop.

Thanks for your help in advance.
