Hi Guy
Another thing to always verify as it has bit me a couple of times. If creating a new project or solution, verify the project dot net target framework is NOT set to client profile. This is a limited dot net and is not supported by all the MM framework.

>>Hi,
>>
>>I have been using MM.Net 4.0 in 64 bit Windows 7 for some time now. All the sudden the MM.Net project wizards are gone from the interface. When I click NEW | PROJECT and select MM.NET... I only have one entry and that is for 'Entity Framework Business Object Library' for c#. I used to have entries for Business Object Projects, WPF Projects, Windows Forms projects, etc. Now they're all gone.
>>I still have the 'MM Business Layer Generator' under the TOOLS menu. And when I open my WPF project I still see MM.NET WPF controls in the toolbox. It seems like it's all there and working normal except the the new project wizards are gone.
>>
>>I have uninstalled and resinstalled MM.NET 4.0 multiple times. Both with reboots and no reboots... and no change. MM.NET Project Wizards don't appear. I have also reset the environment a couple times to test that. Still no results.
>>
>>Not sure what to try next. What could be going on? Any ideas how I can get my MM.NET Project Wizards back?

>>Thanks,
