Mark:
Thanks for your reply. I'm using the Python extension described here:
http://www.synapseadaptive.com/joel/index_old.html
Basically, the natlink.pyd file is called ( after being registered with
regsvr32 ) indirectly by the speech recognition engine. Thus, if the
natlink.pyd file is built using, say, Python version 2.6, and I have
another version of Python installed, say, Python version 2.7, then when
the functions inside of natlink.pyd are called, they need to somehow be
able to figure out the correct Python path and other linked libraries.
So, I'm not sure how this works in terms of the registry and how Python
figures out which Python version it should use and where the
corresponding libraries are.
Any ideas here? I would like to have multiple Python installations on
the same machine so I can migrate between two versions, but I admit all
of this registry stuff is confusing to me and I don't imagine it will be
so simple as simply changing the Python path.
Thanks in advance and for all your great work bringing Python to us
Windows users.

Hi,
I have been researching this for a couple of days now, and although
virtualenv seems like the answer, I have been reading about problems
with applications that require specific versions of Python in the
registry so it can find corresponding PYD and DLL files. This means that
it is more complicated than just setting the path differently for each
Python installation.
I'm not with you there. What problems specifically?
In other words, if you need
c:> regsrv32.exe Some_python.pyd
regsvr32.exe doesn't work with .pyd files - what were you hoping to
achieve?
then they're going to be problems if you try to change your default
Python installation by just manipulating the Path.
Basically, my problem is I need to slowly migrate my entire software
stack from Python version 2.6 to Python version 2.7.
What specific problems are you seeing?
Mark
