Solution 3

Ensure that the UAC is turned on in the server.

Solution 4

Make sure it already has SharePoint Designer 32-bit version installed. The appropriate version of Office Suite is 32-bit as you can’t mix versions of Office components. You may have installed SharePoint 2010 Foundation 64-bit version. And here is the problem – you have 32-bit Office components and 64-bit SharePoint 2010 Foundation.

Ensure that the versions are the same.
