Pysvn installer fails to detect Python installation

Question

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 kits. Pysvn Windows installer aborts on

pysvn requires Python 2.7 to be installed.

Quitting installation

I've tried both installer files, py27-pysvn-svn1612-1.7.4-1321.exe and py27-pysvn-svn1615-1.7.5-1360.exe. Neither of them works.

How can I convince the installer that I have Python 2.7 installed? How is the installer determining whether pysvn is installed or not?

Answer 1

Did u perhaps install the 64-bit version of Python? If yes: Try the 32-bit installer.

Background: It seems like the 64-bit installer doesn't properly set the correct values in the windows registry (which is the place where PySVN tries to find Python).

Answer 2

I tried this and it worked perfectly:

Copy HKLM\SOFTWARE​\Pyt​ho​n\Pyth​onCore\2​.7\In​​stallPath to HKCU\SOFTWARE​\Pyt​ho​n\Pyth​onCore\2​.7\In​​stallPath.

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.
