How to include Python and pyserial installation in a TestStand MSI deployment?

[SebastianBengtsson]

Hi

We are developing a production test system based on:

• TestStand 2019
• LabVIEW 2019 (for some PreUUT and PostUUT actions)
• Python 3.8 (for code modules)

We already have two MSI deployments for almost all parts (including runtimes for TestStand and LabVIEW), based on NI's best practices:

We are now trying to figure out if we can include the installation of python and pyserial in our MSI deployment.

Specifically, the production machines must have the following installed:

• python-3.8.3.exe
• python -m pip install pyserial (executed in Command Prompt)

What is the recommended way to achieve this?

Answering my own question.

I used Custom Commands to execute third-party installers, as described here:
