install - py launcher does not find my Python 2.7 -
i'm on windows 7. have python 2.7 installed years. installed python 3.4. i'm trying use new py launcher. when open cmd terminal , type py -2
, error message: requested python version (2) not installed
. how can make py aware of python 2.7 installation?
note: python 2.7 installed in non-standard directory (not in c:\python27), in case problem.
i found solution. registry had wrong entries. have 32 bit version installed went hkey_local_machine|hkey_current_user\software\wow6432node\python\pythoncore\2.7\installpath
, value set c:\python27
while installation in d:\python27
. changed registry values match correct location , works fine.
it's been quite while installed python 2.7, assume had python 2.7 installed first. deleted , installed pythonxy in new location. didn't uninstall previous version correctly.
