Any ideas on why Open() would fail?

[BReeves]

I sent her a test app with a test of VLDSCapture1->Opened after the call to VLDSCapture1->Open(); to see if it returned true. It returned false on her machine but returns true on mine.

No error, it simply doesn't populate the check list because VLDSCapture1->VideoSources->Count returns 0.

Apreciate you trying to help but really don't believe it is an issue with my code as it works on everything but this one computer. I have had her reinstall the capture card drivers, update ActiveX and even reinstall the video card drivers thinking it might be something in one of thoes but no joy.

Received an email from her this morning, she is going to try to restore the computer back to the as-shipped state and reinstall the software. This may just fix it.. At leat I'm hoping it does.
