Another team created python scripts within our organization for my team to run. Up until two weeks ago, we all ran them without any problems. Then one day, some users have been unable to run them successfully on the same machine.
All users are admins with LUA disabled. All users should have the same permissions. 
The complicating factor here is the team created a "framework" which generates code from a combination of the framework, and an excel file for the tests being run. This prevents me from stepping through the code and finding where it's specifically failing. Beyond that, the same exact script runs on the same machine when another user trying to run it.
Specifically, in the script, it appears that when the affected users are running the script, IEDriverserver doesn't appear to open. No errors are given.
Is there any environmental variables that could be specific to users that would cause this? Even a direction to look would be extremely helpful.
I encountered the similar issue today. I happen to solve it by unset PYTHONHOME and PYTHONPATH. Not sure if this helps.
Python script works for one user, but not another on same machine
