Upon execution of python.exe a command line box appears for a fraction of a second, closes and is followed by nothing. On executing IDLE from the start menu, nothing happens. I have installed python to C:\Python27 using the python windows installer.
I am running win7 64 bit on a toshiba satellite 17X
ezio-melotti commentedon May 21, 2011
Can you try to open a Windows terminal (start->run->cmd or win+r on the keyboard), cd to Python27, execute python.exe and see if it gives any error message there?
PhilipDrew commentedon May 22, 2011
The error message is:
ImportError: No module named site.
ezio-melotti commentedon May 22, 2011
The 'site' module should be in Python27\Lib\site.py.
You could try to run "python.exe -v" to see if it says something useful in the output, or maybe try to reinstall Python and see if it works.
PhilipDrew commentedon May 22, 2011
The site module is in the right place
This is what I got running the -v flag: (I don't know what you're looking for)

Reinstalling makes no difference- have tried multiple times
tjguk commentedon May 23, 2011
What happens if you try "python -S" (capital S)? In principle this should bypass the need to load site.py. Even if that works we still have a problem to solve, but at least it might narrow things down.
PhilipDrew commentedon May 23, 2011
Gave it a go: the prompt appears, but none of the functions work thereafter

From a Windows command prompt:
PhilipDrew commentedon May 23, 2011
C:\Users\PWTD>set PY
PYTHONHOME=c:\program files (x86)\steam\steamapps\common\alien swarm\swarm\..\sdktools\python\2.5
C:\Users\PWTD>chcp
Active code page: 850
C:\Users\PWTD>
amauryfa commentedon May 23, 2011
hmm, I don't like this PYTHONHOME. Can you reset its value and run python again in the same terminal?
C:\Users\PWTD>set PYTHONHOME=
C:\Users\PWTD>c:\Python27\python
PhilipDrew commentedon May 24, 2011
Ok, python now works in command prompt, but IDLE still wont run.
Also, PYTHONHOME needs to be reset on every start up of command prompt.
amauryfa commentedon May 24, 2011
Yes, this is probably a system-wide setting. PYTHONHOME should not be set, especially if it points to another python installation.
You should consider removing it.
Is "alien swarm" a game? Why did it modify the system this way? Does the game still work when you remove the environment variable?
PhilipDrew commentedon May 24, 2011
Awesome. It's fixed- do you still want to know whether or not the game works.
In case it helps, I installed the game before python
amauryfa commentedon May 24, 2011
It's definitely a bad thing to set PYTHONHOME at the system level, when there are several pythons installed. Please report this to the game's developers.
