I look after a Delphi program that uses Python 2.5 (via Python for Delphi). A customer who uses a modeling program that requires Python 2.7 experiences a Python conflict when trying to run the Delphi program. I have installed both Python 2.5 and 2.7 on a test-bed computer and can run the Delphi program. I have searched the FAQ, and have found some mention of being able to set a default Python version when installing, which I presume has occurred when the customer installed Python 2.7, so that the Delphi program is being directed to Python 2.7.
However, I do not see this option when I install Python 2.7, and I do not see how to remove this option so I can advise the customer what to do. The programs are running under Windows 7 - 32-bit. Any assistance gratefully received.
