When we start our application we get an error which, when we use the Debugger, returns a message of "hkQueryDirectoryFile:Skipping virtual file: 'xyz.exe' because it doesn't match FileMask". Can you please elaborate what would cause this message to be triggered? Interestingly, when we use the 'Run As Administrator' option (Win 8.1) the error does not occur in our application and the message does not appear.
