this was working recently. this is on Windows 10 with all latest OS updates

problem may have started after recent OS update?

Try to launch the program from a command line in a terminal, not from Python, to see if it works as expected.

[davecotter]

it does not work in terminal either.
note that it is on a network mapped drive, but that should not affect things, especially because i explicitly allowed that intratnet zone

[davecotter]

when i move the AutoPin.exe to an internal drive, it DOES work. so it has something to do with the fact that it's on a network-mapped drive. but see my screen shot where you can see that i EXPLICITLY allow running apps from that drive
