Python 2.6.6 on Windows 7 problem - "ImportError: No module named site"

[Mark Ohrboot]

Hello!

If I start python -v, I get

"# installing zipimport hook
import zipimport # builtin
# installed zipimport hook
'import site' failed; traceback
ImportError: No module named site"

Entering any command yields
"LookupError: no codec search functions registered: can't find
encoding"

I reinstalled it, but this makes no difference. Any suggestions?

Thanks
Mark
