Running NCover on a 64bit machine

At a customer we are not using the Visual Studio Code Coverage feature to measure the unit test code coverage. Instead we are using NCover. As we are migrating from CruiseControl.NET to TFS Build, we installed NCover on our fresh new build server.

Running the build resulted not in an all green report but in the following error:


“System.DllNotFoundException: Unable to load DLL 'NCover.Lib.x64.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)”


On the NCover forums, we found a solution for our problem. We accidently installed the x86 version of NCover on our 64bit build server.. Although it might work in some cases, it is not a supported configuration. So we removed the x86 version and did a clean install of the x64 version of NCover. This version includes both the 64-bit and 32-bit installations.
