Post-install errors while installing pywin32-216 on Windows XP

I'm using the pywin32-216.win32-py2.6.exe package to install pywin32 on Python 2.6.5 (r265:79096, Mar 19 2010, 21:48:26) [MSC v.1500 32 bit (Intel)] on win32. I am seeing the following post install errors. Could someone help me understand what going wrong? Thanks in advance.

Most probably pywin32 requires administrator privileges to be installed successfully. I am not sure how to do that on WinXP, but Microsoft has a page about it.

I managed to fix the problem by eventually cleaning all traces of Python 2.6 from my system and re-installing it + pywin32. It was eventually as simple as just double clicking the setup files.

Another answer for the googlers:

I has the same issue, it turns out it originated because I have installed python in the past, removed it and reinstalled it to another location. In order to solve it I had to:

1. Remove old installations (Uninstall + manually from registry) - as Danish advised (both in main root and in Wow6432Node).
2. In the registry update the location of current location of the python folder path (in InstallPath and PythonPath).
