Then went nothing more, no matter what I tried. I have deleted the folder and to download again performed again with the same result. Then I have the previous protection disabled and the durchgefüht Downlaod one more time. The result was the same error message again. Finally, I downloaded the trial version, as I now stood without Internet protection. After several unsuccessful attempts, I was frustrated, but too angry to give up. Finally, I had the idea to enter the activation code from a trial, and then the installation has finally worked.
Instructions:
1. Kaspersky Internet Security open (either the previous version or the trial version)
2. If you open Kaspersky, the lower right corner: "License: (just so many) days left" in green -> click.
3. Once you have the "License ..." is clicked, you will be redirected to the "License management". There is a heading "Reserve Enter Activation Code" and including "Enter activation code".
4. "Enter Activation Code" button. Here is a 20-digit activation code, which consists of capital letters and numbers. The activation code can be found under "Amazon Games & Software Library" as a "serial number". Once I did that, did with me everything is working properly.
I wish you all good luck and a successful installation!
