TortoiseGit - git not found

While this question is still hot... some nice people contributed lots of bugfixes to all three projects, so this is what I did to get TortoiseGit on Win7x64, previously failing on all combinations:

1. install mSysGit (network installer) into C:\msysgit, it will download the source and compile it leaving you in a bash git prompt. Stable version: msysGit-netinstall-1.7.2.3-preview20100911.exe 13 sep
2. install Git “preview” into C:\Program Files (x86)\Git, choose OpenSSH for ssh link Stable version: Git-1.7.2.3-preview20100911.exe 13 sep
3. install tortoisegit into C:\Program Files\TortoiseGit, (x64 version) and configure it’s settings specifying the git path (C:\msysgit\bin) and menu integration. Stable version: TortoiseGit-1.5.6.0-64bit.msi 25 sep

This setup picked up my existing git repos made on WinXP x86 with older versions of the packages, and seems fairly stable and fully functional.
