How to run WD Red SMART load/unload utility in Windows 8.1

Am trying to update WD20EFRX firmware.  Have downloaded the WD5741.exe and tried to follow instructions with no apparent success.

.I am running Windows 8.1 on a Kingston SSD and have the WD20EFRX plugged in as an additional drive on the PC.  I open a command window and navigate to downloads, do a dir and I can see the WD5741.exe.  When I try to run it using the switches specified in the instructions on the download page, another command window flashes briefly on my screen then closes.  What am I missing or doing wrong?

Couple of odd things, tried to download WD5741x64 first but Win 8.1 just opens the file in Notepad, all gibberish.

Any thoughts welcome as I have several of these drives to update before putting them in my new (to me) NAS.

Thanks for any info.

Open the command prompt with administrator priviledge.

That did the trick.  I thought my user accoutn had admin rights but running as administrator solved the problem.

Thanks
