Re: HKLM\Init and MFC Application (further clarification)

Yes, I'm not surprised that it shows as 'read only' in the image, since it's
presumably in nk.bin. I'm out of ideas. You could use one of the support
requests that comes with PB and see if MS support can get you an answer.

I think that Brian might very well be right about the 50 not found error
coming from MFC trying to open it as a file name. Don't forget to call
SignalStarted() with that value...
