Hello,
I've tried to setup a test server for CMS 7.5, I've correctly download SIM from trialware link, but after keying my contact info, I wasn't able to download anything.
I've received a pop-up with some products listed and this error message :
"Products were unable to be verified for download"
After some tries and changes, I've discovered that even if OS language was English, my user was using French localization settings.
So just changing in control panel/ Region and Language the format to English (United States) solved my issue, and now I'm able to install CMS 7.5
Hope it will help others,
