Error trying to use Microsoft Win 7 USB DVD download tool app

On a win 7 machine, I am trying to make a bootable USB from an ISO for win 2012R2 essentials

When I run the download tool, the first screen I get says:
Application has generated an exception that could not be handled
process id=0x8dc (2268) Thread ID=0xec8 (3784)

Googling that comes up with nothing.

Any advice on solving the error and / or another way to make the ISO (already downloaded - 4+ GB) into a bootable USB drive (on an 8GB thumb drive I have).

I tried installing the download tool on a win 10 machine I have and it wants .net v2.0 installed.  

Didn't go that route yet, but that might be an option?

Use an OS that supports mounting ISO files as a drive. Win10 can do this, for example. Then format the USB stick and make sure to set everything to default. Block size, etc. Then simply copy the files using windows explorer from the mounted ISO to the USB drive. It's painless.

The error you are seeing is from a corrupt .Net store so you may have other issues with that computer. Ultimately I'd consider formatting and reinstalling or upgrading it. But this is a quick workaround and doesn't rely on .Net at all.
I have had good experience with the Winsetup from USB tool. The new beta version is also supposed to support wims or iso's over 4GB size, but that part I haven't tested yet. It has further advantages, as you can mix several iso's on one stick, and it also supports linux iso's:
