We have several users that are experiencing the following:

Python 3.14 installed in default location

Python added to PATH

TestComplete launches and prepends its own Python to the PATH and causes users tests to run.

I need to stop TC from adding to the PATH when it launches.

Thanks in advance.

If you run Python scripts via TestComplete, then it needs to use it’s own Python package. TestComplete supports Python 3.13.3
