My Studio doesn't work and doesn't open (due to problems with an old GroupShare customer which is not more available), so I removed Studio from programs and wanted to install again. I also downloaded new .exe file from my old order on website again but it is not possible to install it. There appears an error message: "Setup did not complete. The error is: Setup has detected a higher version of this product already installed. If you wish to install this version, you must remove the other version first."

But I don't have any other versions on my computer!!! So I don't know what to do.

I tried to deactivate my license offline, I received the offline deactivation ticket on my e-mail but what do I have to do with it if there is no more Studio on my computer and installation is not possible?

I also tried to reset the license, but it resulted with error message on website.

Then I just installed the same downloaded Studio exe.file on another computer but there is only trial possible.

What do I have to do? At the moment I better want keep Studio on my old computer.

If it is not more possible, then on the other one. Please help!
