Please check Pyarmor installation documentation.

I dont see anything in the installation documentation that mentions this bug, besides that i did a clean pyarmor uninstallation and installation and the error persists

[jondy]

Make sure this wheel pyarmor.cli.core-5.4.3-cp312-none-win32.whl is installed by checking pip log

[danvelezsan]

pip list 
Package          Version
---------------- -------
pip              24.0
pyarmor          8.4.7
pyarmor.cli.core 5.4.3
setuptools       69.1.0

[jondy]

Got it. It will be fixed in next release.

[jondy]

As a quick workaround, download http://pyarmor.dashingsoft.com/downloads/temp/win32.x86/py312/pytransform3.pyd http://pyarmor.dashingsoft.com/downloads/temp/win32.x86/py312/pyarmor_runtime.pyd

Then overwrite /path/to/pyarmor/cli/core/pytransform3.pyd and pyarmor_runtime.pyd

[jondy]

Fixed in v8.5.0
