(V7) Install / Uninstall issue

Today I gave V7 WIP a try.
I played a bit around.

Then I wanted to work in V6.

The German language was gone.
Also not to switch in the options.

So I uninstalled V7.

Surprise, the V6 license is gone (stored locally).
I had to re-enter the code and let the validation do it’s things.

I tried a repair install of V6.
Still in English, and no other language available.

Before I now have to uninstall V6:
How to get the German back?

Thanks.

Run the installer again, but now select Modify instead of Repair.

After selecting the language, I get this:

Bootstrapper?


Ok, selecting the exe in the folder worked.
Language is ok now.

Thank you.
