I am trying to connect via USB the PCA10001, but my windows 7 says that the driver is missing. My question is, Is the error from the image a problem for the drivers?en-USTelligent Community 13Fri, 24 Oct 2014 15:08:45 GMThttps://devzone.nordicsemi.com/thread/14294?ContentTypeID=1Fri, 24 Oct 2014 15:08:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a24701d6-8a53-4aa7-aa6d-684f034fba25michel<p>Yes, I got the error again. I figured out that there was a problem with my operating system. I installed everything on another pc and it worked!

Clear the temp folder (C:\Users\Michel\AppData\Local\Temp). At least delete the PROPSYS.dll file. Download a new copy of nRFTools from the Nordic website (in case the last download was corrupted). And install. Do you still get the error?</p><div style="clear:both;"></div>
