Hi
We have some production equipment still running windows 7. We would like to update the nrf51 dongle to a nrf52 dongle.
But drivers for nrf52 dongle is not installed correct although I have installed the newest version of nrf connect? Isn't it possible to use a nrf52 dongle in windows 7?
In windows 10 its not a problem to find the dongle.

Hi Jonathan
Thank you very much for your reply. Now something interesting happened
But still it cannot find the device in nrf connect
Thanks for the details,
Since i do not have a w7 device to debug on and that w7 is end of support, it is not something we support any more either. And the nRF connect for Desktop app does not really support w7. 
I do see that this is a big inconvenience. So will try to find a solution but i currently do not have a win7 computer to test on.
Could a issue be that the win7 computer you have has many instances of devices, more then 200-250? If so then the amount of ports in use might be causing strange behaviour. Dont think this is the issue but can be good to check.
You can try to downgrade the nRF connect for desktop version maybe and see if that solves the issue.
You can find previous versions here Releases · NordicSemiconductor/pc-nrfconnect-launcher · GitHub
Since the device showes up as a USB CDC and Nordic DFU device i do find it strange that it does not showe in the Desktop app.
Regards,
Jonathan
Hi Jonathan
I also thought of that since the dongle gets COM30. But it is not changeable
if I take another device that have have changeable port then I see that up to 32 have been in use
If I try to install older version of nrfConnect i get this error message
Our test equipments have older versions of windows since our product lifetime is longer than the lifetime of windows versions. And we don't add new value to our products but only a lot of work by updating all instrument drivers and test sequeneces by updating windows version. Therefore we have some test equipment running windows 7.
