Which installer did you use, e.g. the latest v5.3? This to see what we have to test.

(edit) though I think I already see what the problem is. v12 == vs2013, they skipped v13 and v14==vs2015, v15==vs2017, so the range should start with v11. It's odd though, we tested it on vs2012 before release. It's still good to learn which version you're installing however so if you could give us that info that would be great

I am trying to install v531

This has been fixed in the hotfix builds v5.2.5 and v5.3.2

If you're a trial user, please run the attached vsix to install the designer inside vs2012, or you could opt for running the designer stand-alone (it has all the features of the integrated designer).

(be sure to unblock the vsix file in windows explorer -> right-click it -> properties -> unblock, if windows blocks it)

Yes, I am a trial user.

The attachment worked.

I will check the application next following the tutorials you have on the web.
