Install VS2010, updated solution, Isolated tests won't run

I installed VS2010 and updated a solution that was in 2008 and had loads of Isolated tests.

When running tests I get:
Test method ... threw exception:
TypeMock.TypeMockException:
*** Typemock Isolator is not currently enabled.
To enable do one of the following:

* To run Typemock Isolator as part of an automated process you can:
- run tests via TMockRunner.exe command line tool
- use 'TypeMockStart' tasks for MSBuild or NAnt

* To work with Typemock Isolator inside Visual Studio.NET:
set Tools->Enable Typemock Isolator from within Visual Studio

For more information consult the documentation (see 'Running' topic)

There is no 'Typemock' menu in VS2010. I have no problems running in VS2008 on other projects. Upgrading to newest version on Typemock is not a path I can take (running 5.4.4).

Also in a new project in VS2010 I had to add references to Typemock via Browse tab, it use to be under .NET tab - is that a bug in VS2010?
