Community Edition - Failed to load module xm_python.dll
Running nxlog-ce-3.1.2319 on Windows.
2023-01-19 08:12:46 ERROR Failed to load module from C:\xxxxx\nxlog\modules\extension\xm_python.dll, The specified module could not be found. ; The specified module could not be found.
The NXLog Python DLL is on disk so I am wondering if this is complaining because I don't have the nxlog Python module (which I don't see in pip).I looked around for some setup instructions but I don't see any extra setup steps required for Python (aside from writing the script).

Hello,
do you have python installed on Windows?
That's a separate required step. It needs python 3.10, and Python executable MUST be in PATH.
The python install and configuration script below has been tested w/ NXLog Enterprise Edition. It will be included in the next revision of NXLog Enterprise Edition documentation, and I will try to squeeze it into the Community Edition docs as well.

Manual steps:
- Download Python version 3.10 (I checked the version on nxlog-ce 3.1)
- Execute the installation wizard and in the first step, choose Customize installation.
- Set “install for all users”
- Set “Add python to environment variables”
- Take note of the install location and click Install.
- When the installation is complete, open the Python installation folder.
- Copy the Python DLL, e.g.,
python310.dll, to the NXLog installation folder. - Rename the file to
libpython<major_version>.<minor_version>.dll. See the table below. - Restart the NXLog service.
This is what the script above tries to do.
Let me know how it goes!
