AnkhSVN is not showing as a source control plugin in VS 2008 on windows 7 (64 bit)

I installed AnkhSVN without error and when I open Visual Studio I don't see AnkhSVN as an available Source Control Plugin. The list is empty.

I've tried the usual - restart VS, reboot, repai开发者_高级运维r installation but it won't seem to

Is it anything to do with me having 64-bit windows 7?

The registry location that I believe Ankh should be adding itself to is:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\9.0\SourceControlProviders\

and not

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\SourceControlProviders\

There are at least thousands of users using AnkhSVN under Windows 7 64 bit without any problems. (And I'm one of them).

If you are just using an official MSI to install AnkhSVN (2.0, 2.1 or 2.2) you shouldn't have any problem.
