This error is from eM Client?

Maybe download the installation file again from http://www.emclient.com/release-history and see if installing that makes any difference.

Yes, and I forgot to mention that I uninstalled and reïnstalled the client again several times…
Thanks anyway for the reply.

This is installed on Windows, or you are running it in a virtual machine?

Windows 10

The error you quoted refers to Fusion, which as far as I know, is a virtual machine for running Windows on Mac hardware.

If that is not the case, and this Fusion that is referred to in the error is something else, maybe try uninstalling Fusion and then try again.
