Very unlikely. If python is told to execute a faulty script (or even
arbitrary, non-python file), python would fail would fail with
"SyntaxError" exception.

Your error message tells that either Python itself has crashed or
Windows refuse to execute python.exe since it detected that python.exe
is not a program.

How did you install python? Did the installer or the machine crashed
half-way through installation? Try reinstalling Python, make sure you
download the correct installer.

Can you start the interactive interpreter? Try starting just
C:\Python26\python.exe (without script argument)
