Thank you Brian. I figured out how to get the data from the binary table. But I'm still not able to find how to append data to the custom action data.
Also, I'm getting return code 6(I'm guessing invalid handle) for MsiGetProperty(). I don't recall any change to my code which would cause this. Any idea in what all conditions I might get this error?
