I am installing nRFTools_6_1_0 and I get this error during the instalation.
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?
Try to uninstall nRFTools and the Segger J-LINK drivers. 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?
