TestProject provides 64-bit Windows agent. We do not have a 32-bit agent.
A possible solution for users with 32-bit operating system, would be to install the TestProject agent on a cloud machine.
For example, you can setup a EC2 instance on AWS and install the agent on it. For more information and a step-by-step tutorial, you can check out this blog post: https://blog.testproject.io/2019/02/07/setup-cloud-test-automation-lab-using-aws/
