Apparently, the setuptools msi is looking for the Python installation registry value InstallPath in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore\2.6\InstallPath. Notice the Wow6432Node, which is a registry compatibility layer used for 32-bit apps in Windows 7 64-bit.

As far as I can tell, InstallPath is the only value that this installer looks for. Therefore, using regedit, you can create your own registry value HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python\PythonCore\2.6\InstallPath, and copy over the InstallPath value from HKEY_LOCAL_MACHINE\SOFTWARE\Python\PythonCore\2.6\InstallPath. To be paranoid, you can try replicating the entire cluster, not just InstallPath.

After this, installation for setuptools seems to proceed correctly. Note that this may only install 32-bit libraries -- WoW6432 is a compatibility layer. Check the other documented solution to this problem if this is not sufficient.

Hopefully they'll fix this bug at some point, though the "not my problem" bug punting so far at the Python tracker and the Setuptools tracker makes this look somewhat unlikely.

  1. This is the right solution; to make life easier I follow this expanded version of the "replicating the entire cluster" solution:

    Step 1: Launch regedit.exe and locate the key "HKEY_LOCAL_MACHINE\SOFTWARE\Python".

    Step 2: With this branch selected, go to the File menu and select Export. Confirm that the "Export range" radio button is set to "Selected branch". Navigate to the directory in which to store your export, provide a File name (I used 'Python') and click "Save".

    Step 3: Open the export file in your favorite editor, and insert the "Wow6432Node" folder between "SOFTWARE" and "Python" so each line begins "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Python". Save the changes.

    Step 4: Double-click on the modified export file and Merge this registry data.

    Problem Solved!
