Cannot run a precompiled example hex file

[junma]

Hi all,
I have one PCA10040 board, and want to start to download and run some examples while reading the on-line documentations.
In section "Running precompiled examples ", I see the description of copy and drag an existing hex file to the standard USB drive. I've tried several times to copy and drag hex files to the USB drive, however, each time after I dragged to the drive, seems the USB drive will reset and delete my dragged hex files. Attached is the capture of the USB drive.

Is there any procedures that I missed? Hope someone can help me about this issue. Thank you in advance!

Best regards.
junma

I found the issue: windows10 pro account type.

I use a windows 10 pro standard account for myself and this is where I have worked and developed, using all kinds of tools, compilers, ide's, and so forth. As usual, I installed all of the new Nordic stuff from this account, entering the Admin password when necessary. And below you see the problems encountered - bizarrely, things enumerated and pretended to work with no errors or warnings or issues with device manager, etc. Actually, it was worse than bizarre ... crazy making, really.

I wish I could attach screen shots where you can clearly see that for the standard account, the nRF52-DK enumerates just fine and pretends to act ok (including the drag and drop of a precompiled hex, but no action), yet nRFgo studio never sees it (I did not know what to look for in nRFgo studio, so I didn't notice what was missing).
