Hi,
I was trying to see if there was something else causing your issue other than Win10.
I can attest that the method you wanted to use works fine on my Win7 installation.

I'm glad you found a workflow (similar to the one I suggested) that is a suitable compromise.
If you have to support Win7 and Win10, a check of the operating system could allow you to add full functionality to Windows 7.
