OK, I was able to install 6.004 Free version.
But it did not help to install 7.0 RC5/6,
because error message says about Professional version 🙁

Before you do this, make sure you save backup of the whole Registry of your system!! To do that, run regedit.exe, and select the root folder and right-click, Export.

Then search for “EmEditor” in data under HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstall, and make a note of the key name, or copy to Notepad. The key name looks like {51371ACB-404F-471D-A669-D93BBC81F8B7}, but yours can be different. Delete that key, and also find the same key name in data and values in other places in the Registry, and if you find any, delete them also. I don’t guarantee this works, but you might want to try it.
