Free/Trial version complains Win 7 Pro is "Enterprise/Server"

[admin]

I'm a new user and want to try out the product.  I might purchase a license in the future, but I can't get my first try to even start as the free/trial version is giving me the following message:

 "The free/trial version doesn't support Windows Enterprise/Server operating systems.(0x0000010708AB0000)"

I'm just trying to install Windows 7 Pro.....is that supposed to be restricted in the free/trial version?

Am I doing something wrong?

Screenshot attached of page where I'm selecting the version to install:  hitting the next button gives a dialog with the message above.

Thanks for any insight or tips to get it to work.

Maybe your host Windows OS (windows run WinToUSB) is the Enterprise/Server edition.
WinToUSB is free for non-commercial use only, it can't run on a Enterprise/Server Windows OS, so please try it on another computer.
Thanks.
