We are having severe problems in upgrading CMS to version 7
1. Entering EpiServer Deployment Center
2. All action tab -> Upgrade site with SQL Server database
3. Error occurs, as in detailed screen output below and the installation process is stalled.
Screen output (text put in bold below is coming out red on screen):
Add-PSSnapin : Cannot load Windows PowerShell snap-in EPiServer.Install.CMS.7.0
.586.1 because of the following error: Could not load file or assembly 'file://

CMS.dll' or one of its dependencies. This assembly is built by a runtime newer
than the currently loaded runtime and cannot be loaded.

Any help is appreciated
