When opening Model.bim in Visual Studio 2012 (with update 2 installed) I got an error Class already exists and in the application log the Event ID 25 was also logged saying The description for Event ID 25 from source MSOLAP$LocalCube cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: msmdsrv.rll 4105 4105 is locale ID corresponding to English (Canada). When I changed the language settings in Control Panel to English(US) the errors is gone and I can successfully open Model.bim file
