Hello all...
I'm at a bit of a loss here. I've recently re-installed Mach3 (after a total hard drive loss), and I am no longer able to use any of the OLE/COM automation features from my code, or from examples that also used to work (ie. the C# MachRemote). I've called /REGSERVER on mach3.exe, and using a viewer, I can see that Mach3 is in the ROT when running (as a GUID, not a normal name mind you)... But really can't get any further. The failure is always at the GetActiveObject("Mach4.Document") calll - which returns saying invalid CLSID. Anybody have any suggestions at all?

Thanks so much,
Brad Parcels

For what it is worth... I've managed to get this working. For some reason, there was a few missing registry entries (despite several re-installs w/ admin permissions etc), specifically the HKCR\Mach4.Document entry.... No matter what I did, I wasn't able to get the program to create the entry itself (anyone know why?), but by exporting/importing the key from another computer that had Mach3 installed, everything is groovy again.

Cheers,
Brad

Brad,
You have fixed the problem I am having. Not finding the ""Mach4.Document" entry!  Can you please detail what you did to fix the problem...
THANK YOU!
