Python version 2.6 required, which was not found in the registry

by

I realize this question is a year old – but I thought I would contribute one additional bit of info in case anyone else is Googling for this answer.

The issue only crops up on Win7 64-bit when you install Python “for all users”. If you install it “for just me”, you should not receive these errors. It seems that a lot of installers only look under HKEY_CURRENT_USER for the required registry settings, and not under HKEY_LOCAL_MACHINE. The page linked by APC gives details on how to manually copy the settings to HKEY_CURRENT_USER.

Or here’s the PowerShell command to do this: cp -rec HKLM:\SOFTWARE\Python\ HKCU:\SOFTWARE
