Our product uses SerialTools to create a virtual serial port. A customer pointed out that he's unable to create a virtual serial port on his Windows 7 64-bit PC. Further inspection showed that an exception occurs, stating, "Failed to Create Virtual Serial Port"
Our software installs on a PC, placing the bizVSerialInt.sys driver in C:\Windows\System32\Drivers and a couple other dll's in a relative folder.
I installed GPSGate and that seemed to fix the problem. But this can't be a solution to our customers. Is there a new driver or dll that gets replaced after the GPSGate installation that our software should be using and placing instead?
