Solution

How will MSTEST know where to find VoterDetails.vsmdi when you are running in the wrong folder; try running from OpenCover from

C:\Users\<<MYuserName>>\Documents\Visual Studio 2010\Projects\VoterDetails

i.e.

C:\Users\<<MyUserName>>\AppData\Local\Apps\OpenCover>OpenCover.Console.exe -register:user ...

also -arch:32 is not a valid option for OpenCover
