Omer, You are not configured to also use a 64-bit Python build are you? The 64-bit Python would not work with the ArcPy site library from ArcGIS 10. Or, did you install ArcGIS 10 or SP1, from a command line with msiexec? If so, check the location of your Python26 install, it defaults to the root of the hard drive with the most space. A couple of ways to adjust things if so. This forum thread has some details.

Any calculation with Python gives me the error msg: Python Not Installed. Both ArcGIS 10 and Python are installed in C:/Program Files (x86). However I am on a network computer, and do not have a 😧 Drive! Would anybody know how I find out where ArcGIS 10 looks for Python on my computer, so I can copy-paste my Python folder there? Thanks! Sid.
