alt-boot-disk-util always fails with device open failed!

[Altera_Forum]

I'm trying to follow this tutorial to generate a preloader for my Terasic DE0-NANO-SOC development board: 

 http://rocketboards.org/foswiki/view/documentation/socswws1introtoalterasocdeviceslab1preloader  I'm using the 15.1.0.185 builds of Quartus Prime Lite Edition and SoC EDS Web Edition on a Windows 10 laptop with built-in SD card reader and micro-SD adapter. I keep trying the following step where the final D is my micro-SD drive letter:  alt-boot-disk-util -p preloader-mkpimage.bin -a write -d D  I always get:    --- Quote Start ---  device open failed!  --- Quote End ---    The SoC EDS command shell is able to navigate to /cygdrive/d without issue and I can browse the contents of the micro-SD card using Windows explorer. I loaded the DE0-NANO-SOC image described by the tutorial as my starting point. The tutorial uses version 15.0. I tried using components built with 15.1.0.185 and had the same issues as well as a different micro-SD card. Has anyone had success/issues using alt-boot-disk-util with these software/OS versions?

On Windows. Yes, works better when you run as administrator. Thanks!

another reminder, do take note for some of the typos in the soceds user guide related with this command, there is a line where the typo showe the wrong alt-boot-disk-util parameter.

C:\altera\15.1\embedded\env.sh also fails to find my qsys directory since I am using the Lite version which defaults to C:\altera_lite\15.1\quartus\sopc_builder\bin. By defining the environment variable QUARTUS_ROOTDIR_OVERRIDE to be the correct path for the Lite version, I was finally able to get the sopc-create-header-files script to run correctly. To the tutorial's credit, 15.1 was not listed as one of the supported versions, but I think the maintainers of the env.sh script should figure out how to handle that right. Also noticed the Windows PATH variable does not get properly imported into cygwin. I have a lot of spaces in the PATH variable, but that didn't seem to cause enough problems for me to worry about it at this point.

I've just been using the command line by right clicking on the embedded command shell batch file and running as administrator. I'm yet to find any examples/guidance that use Eclipse for anything. Every example I've found uses the command line and Makefiles.

I saw there is another forum post also talking about issue related with the Altera lite, it seems that some compatibility issues with this release line.

what is the reason you choose to use the lite version?
