Please try this instead. This should be matching latest ATL version.
pscad = mhrc.automation.launch_pscad(certificate=False)
no license found when Python calls PSCAD
Hi everyone,
When I tried to use Python to call PSCAD using simple example as below, PSCAD could be launched with the login window but it would be closed a few seconds later because of Python failed to acquire license. The screenshot is attached. In the commend window of Python, "Waiting to acquire license" was shown first. After few seconds, it showed "No license found" and PSCAD was closed.
I followed the instruction to select "Retain certificate" before exit PSCAD but this problem still happened. My PSCAD used the dongle license from remote machine. I can run models in PSCAD directly without any license issues. In addition, because the license I used is from employer, PSCAD does not allow me to login with my personal account.
Is there anyone who had the same issue? Could you please let me know how to solve it?
Thanks.

Do you have a USB key? If yes, you need to change your Python script to cl_use_advanced to false.
The Automation Library provides two methods of starting PSCAD: “Manual” and “Automatic”.
The Automatic method, launch_pscad() is easier to use. It will find the PSCAD application and launch it with the most common options as defaults. If more than one version of PSCAD is installed, it will choose one, preferring offical releases over Beta versions, 64-bit versions over 32-bit versions, and later releases over earlier ones. Arguments may be specified to alter these defaults.
The Manual method involves obtaining a controller(), and querying it for the installed version(s) of PSCAD, choosing the desired version from the available choices, and passing that choice to the launch function. After PSCAD launches, the PSCAD.settings() command must be invoked immediately to ensure the correct licensing option, and a license is acquired.

Codes:
# No Certificate exists, set PSCAD to use dongle License
else:
pscad.settings(cl_use_advanced='false')
print("PSCAD is using a Dongle license!")
# Set the compiler
pscad.settings(fortran_version=fortran_version)

Hi Tamer, Thank you so much for your solution but it looks like not working with me. I added one line of code to change "cl_use_advanced" to false, but I still got the same problem, "No license found". I attached the screenshot of both code and error. Is there any place where I made a mistake?
Thanks.
Thanks.
