pynrfjprog can not get_connected_probes on WIN7

[OPQ]

Hi,

I had done a python script using pynrfjprog, and use pyinstaller already created an .exe,and this .exe works well on Windows 10 system PC.

But when I run this .exe file on the Win7 PC,the .exe also can run,but it can't  get_connected_probes when using 

api.get_connected_probes().

I had try pynrfjprog v10.12.0 and pynrfjprog v10.11.0 ,they all not works well on WIN7.

Could you please give me some suggestions?Thanks!

Nothing in specific pop to mind. Are you able to provide more details on the error message/stack trace and python version?

Can you verify that you have installed VC runtime?

Hi Kenneth,

Yes,VC runtime was already installed,and I try 3 different WIN7 computer.

There was no error massage,the script can run witout error,the issue is that when using get_connected_probes() ,will not get the jlink snr which was connected with my computer.

api = HighLevel.API()
api.open()
devices = api.get_connected_probes()

Can you try to make a log:

import logging
logging.basicConfig(level=logging.DEBUG)
api = HighLevel.API()
api.open()
devices = api.get_connected_probes()

This should output logging to console, you may replace basicConfig() with the following to output to a log file instead:

logging.basicConfig(level=logging.DEBUG, filename="log.log")

I don't have any suggestion based on this. I can see Microsoft have ended their support also for Windows 7, so I suggest to upgrade to Windows 10:
