[BUG] PyArmor 8 registration on VM: SystemError: <built-in function init_ctx> returned a result with an exception set

[Kevin-Faeh]

The registration of a PyArmor Pro license does not work on a Windows 11 VM with PyArmor V 8.5.8.
The Exception is: RuntimeError: Incorrect function. See the details below.
The registration works on a Windows 11 laptop but not on a virtual machine.
To note: the registration of an older PyArmor license with PyArmor version 7.7.4 does work without issues on the VM.

(The license id is replaced by XXXX)

The above exception was the direct cause of the following exception:

SystemError: <built-in function init_ctx> returned a result with an exception set

Is it possible that the init_ctx function tries to read out some machine information that are not available in the VM setup?
Thank you for your help!

First make sure this VM could visit internet
Then check the extension works by running the following command in the VM container:

python3
>>> from pyarmor.cli.core import pytransform3

If it doesn't work, make sure there is python310.dll in the dll load path.

Or check it by

dumpbin /dependents \path\to\pytransform3.pyd

Hi Jondy, thank you for your quick response!
The VM has internet access.
The extension works and pytranform3 can be imported.
Here also the output of dumbin:

When debugging the module on the VM, I can see that the exception is raised inside the "init_ctx" function of the pytransform3 (Line 100, pyarmor\cli\core_init_.py)
The only thing that I can see is that before the init_ctx call, the ctx.license_info is the trial license, but after the init_ctx call (although it raises an exception) it contains our license. So the exception occurs after the license readout.
Is there a way how we can provide you more information?

I build new one at
https://pyarmor.dashingsoft.com/downloads/temp/windows/x86_64/py310/pytransform3.pyd

Replace VM venv\Lib\site-packages\pyarmor\cli\core\pytransform3.pyd with this one

And try it again.

This new one will be released in next version 8.5.9

Hi Jondy,

Thank you very much, this worked.
Looking forward to the next release!
