Comment 3 for bug 701512

Hello, tks for the answer.
Yes, I'm so sorry, I forgot to mention the OS: Windows XP Pro sp3 with all updates.

Python 2.6 was installed as per its orginal settings, I didn't change the default installation path and the same condition was for the version 2.7 installation

At the beginning I dind't see the added search engines plugins were missing after Python upgrade, what let me to discover that was IE and FF was not working anymore, any web page I went to open they show me just white pages with no error messages. For that issue I removed Python 2.7 reinstalling 2.6, and here rise the problem described in my first post.

Now I restored a ghost image and everything is fine
