# TestStand 2017 SP1, 64-bit
# OS: Windows 10, 64-bit
I am trying to deploy a test system which uses Python Step Types for TestStand (v.1.0.1). I am able to successfully install the test system on the test machine, but it throws error -17500, exactly as it appears in this KB article:

I am not using NI hardware, so there is no point (as far as I can see) in "resetting NI hardware" per the above KB article.
I am using Python 3.6.8, 64-bit, which I even tried re-installing per another KB article.
I have deployed Python Step Types for TestStand with the test machine as part of the image generated in TSDU and have run the "NIPythonAnalyzerRegisterUtil.exe" on the test machine as advised by the Python Step Types documentation.
An interesting item is perhaps that when Python is not added to the system path, the test is much quicker to fail with error -17500. If Python _is_ added to the system path, it takes several seconds for error -17500 to appear.
