Edited Issue: Could not load file or assembly [65062]

Just downloaded the latest version and when I start the application, I get a popup stating that it cannot load Microsoft.SharePoint.Client.Runtime version 15.0.0.0.

The message continues with Strong name validation failed.

I've tried this on a virtual machine without SharePoint and a virtual machine with SharePoint.

Microsoft.SharePoint.Client.Runtime is in the same folder as the application.

Any ideas what the problem could be?

Thanks
