Please also install pyarmor.core for windows.x86

[pauloswear]

Sorry, but how can I do it? there's nothing in docs

[VeNoMouS]

pip install -U pyarmor.core

?

[pauloswear]

This does not exists in pypi

[jondy]

@pauloswear pyarmor.cli.core is platform-dependent, windows.x86_64 is different from windows.x86, please also install pyarmor.cli.core for Python x86. Suppose Python x86 at c:/Python310-32/python, then

c:/Python310-32/python -m pip install pyarmor.cli.core

@VeNoMouS sorry, I made a mistake, the package name is pyarmor.cli.core, not pyarmor.core.

[jondy]

How about importing pytransform3 directly?

C:/Python310-32/python
>>> import pyarmor.cli.core.pytransform3

[jondy]

After search error message The specified procedure could not be found. in msdn, I think the problem is that some dependent dlls of pytransform3.pyd are missed, please check it by dumpbin

3rd machine (azure virtual private server ws2016) got error too

[jondy]

Download vc_redist.x86.exe and install it may fix this issue

[pauloswear]

not fixed

[pauloswear]

It seems that's some incompatibility with 3.10.x or HIGHER versions

Works:

>>> import pyarmor.cli.core.pytransform3

Not work:

3.11.x

Can you check?

[jondy]

I have no win10 and Python 3.10+ doesn't work in win7.

Could you check the dependent libraries?

dumpbin /DEPENDENTS /path/to/python3.10/site-packages/pyarmor/cli/core/pytransform3.pyd

[pauloswear]

You can use this simple mod:

@pauloswear I found something different from python3.9, I think it need to rebuild python3.10 and python3.11 to fix this issue.

[pauloswear]

Rebuild python or pyarmor?

[jondy]

@pauloswear I rebuild them and upload to
http://dashingsoft.com/downloads/temp/cp3.10/pytransform3.pyd
http://dashingsoft.com/downloads/temp/cp3.10/pyarmor_runtime.pyd
http://dashingsoft.com/downloads/temp/cp3.11/pytransform3.pyd
http://dashingsoft.com/downloads/temp/cp3.11/pyarmor_runtime.pyd

Could you download them and replace the old ones and verify it works or not?

[pauloswear]

@jondy It solved, thanks. Will open different topic for other questions
