I have Python 2.7.2 installed in the default location, C:\\Python27. I\'ve downloaded pysvn 2.7 from http://pysvn.tigris.org/project_downloads.html > Windows installation
I tried this and it worked perfectly:
Copy HKLM\SOFTWARE\Python\PythonCore\2.7\InstallPath to HKCU\SOFTWARE\Python\PythonCore\2.7\InstallPath.
Same link as above, but a different solution is offered within the thread. It is a problem with the pysvn 32-bit installer looking in the wrong (?) place in the Registry for the installed Python version.
Edit: The 32-bit module still didn't work correctly with the 64-bit Python. The only solution for this is to use 32-bit Python with the module.
