nRF Connect 3.6 Windows 10 ERROR Error while probing devices: Error occured when get serial numbers. Errorcode: CouldNotCallFunction (0x9)

I've reinstalled several times. nRF Connect recognizes PCA10100 at serial COM8 but all the read/write functions are all grayed out

Just tried this on a MacBook Pro with no prior installation of any nRF software, same issue.  It looks like 3.6 is DOA.  Can't program any nRF devices at all

Hello, 

I'm not able to reproduce this issue on my computer or the department MacBook Air. Did it work before? What are you trying to program the PCA10100 (nRF52833 DK) with? 

What version of the JLink drivers are you using? 

Kind regards,
Øyvind

52833dk, on win10 it was working before before installing 3.6.  on the mac, no nordic or jlink was ever installed on it so there's clearly a problem with 3.6.  However, I fixed both win10 and mac by deleting any trace of nordicsemi/jlink including registries on win10.  Then, I installed 3.5 then that got it to work and then upgraded to 3.6 from the UI.

My apologies for the late reply.

So, the issue has been solved? I've never seen or heard of this issue before. I will investigate some more on my side.
