I am using the July CTP.
I am building a test ATL control, so very simple.
It seems that to register the control I have to have built a manifest. If I turn off manifest contruction then the registration fails with error PRJ0050: Failed to register output, check security....
Attempting to use regsvr32 produces error 0x80070716 - specified respource name cannot be found in the image file
I think this is something to do with the new registrationless COM side-by-side stuff. However, I am perfectly happy to register and don't want all this new stuff.
How do I make it work the 'old' way
All this is not helped by one of my developer machines producing an error with mt
