Premium License not working on new laptop

[NilsL]

Hi,

I have just installed Backyard EOS on my new laptop. When starting up the software I get an error message "Ungültige Klasse" in German, which translates to "invalid class".

I have a premium license that worked fine before on another machine. Can you tell me what the reason might be?

Regards,

Nils

Do you have the required version of the .NET Framework installed on the new laptop. I believe that it is 4.5.

Have you tried re-installing BYE? Be sure to use the latest version (3.2.2) and in the future please include the version number in your posts.

Did you enter your Premium license key into the validation dialog in BYE on the new machine?

I see some activity on the server in trying to activate your key, and the server is processing it properly.  For this reason, I suspect it could be an installation issue.

Can you please re-install, making sure you download the latest, and try again?

Thank you for not posting your key here on the forum.... yep.... some do that

Keep us posted on your progress please.

Thank you both for the fast response. I will try reinstalling the software and will make sure .NET Framework is installed properly.
I'll keep you posted.

Thanks

A clean installation of Windows 10 did the trick eventually. Must have been something wrong with Windows.
Thanks again for your help.
