I have a proprietary program with a command interface implemented as an

is designed to work with Windows 64-bit only? Is there a version that

Python is available is both 32-bit and 64-bit forms. You can use either
one on a 64-bit operating system.
However, a 64-bit process cannot call a 32-bit DLL, nor the reverse. If
your proprietary program is a 32-bit application, then you need to
install and use a 32-bit Python in order to use it.
You can't install 64-bit product on a 32-bit Windows system, so if you
are having trouble on a 32-bit Windows system, then there is something
else going on.
The interface has a function which returns a string from an array of
strings as it is supposed to
in Windows 64-bit, or if called from VBA.
In 32-bit Windows Python it returns the number of the item in the array
instead.
