Outlook Client installation failed - only upgrade option offered

Hello everybody.

Since the last days I tried to install a Dynamics CRM 2015 Outlook Client on a laptop.

But it failed all the time.

There was a corrupt installation on the laptop before. I cleaned all registry entries, folders like AppData etc..

But i'm getting always the following message while executing the CRM client setup:

It is realy annoying :)

Do you have any suggestions?

Please let me know

Thanks for supporting me
