I maintain a Delphi program, AAA, that runs Python 2.5 scripts using the
PythonForDelphi (P4D)interface. I can install both Python 2.5 and Python 2.7
on my computer and AAA is unaffected. However one user of AAA uses another
program, BBB, that requires Python 2.7. When they run AAA, an error is
generated that suggests that AAA has been directed to the Python 2.7 libraries.
The specific error is identified in Python27\lib\linecache.py line 127
with open(fullname, 'rU') as fp:
as compared with Python25\lib\linecache.py line 128
fp = open(fullname, 'rU')
It appears that the BBB program installs Python 2.7 to be the "default" Python
version, although I do not know how this is done. Assuming BBB cannot be
changed, I would like to know how I can modify AAA so that it ignores any
"default" settings and simply runs Python 2.5.
