| Running Windows 7 32-bit, have the 6.38 version software installed with the 2.0.1 driver for my GQ-4X.
When I launch the USB Programmer app, it opens, looks for new software, says it's updated already, loads the last device and them immediately exits or quits the program.
I try again, somewhere usually between the 3rd to 12th attempt it sticks and it works fine. Sometimes clicking on a command button or menu bar helps to get it not to quit.
Tried removing and reinstalling, same behavior.
