[Bug]: Could not found Ghostscript

[Hellfar]

What were you trying to do?

Hello,

I am trying to use OCRmyPDF in a Python program.

It is basically not finding ghostscript and jbig2.
Where I could not find a proper way to install jbig2 (I mean not from a link from where nothing about the compilation details been shared), I DID install ghostscript and is present from my PATH as everywhere else when I try to use it gs --version it output me 10.05.1.
I do not understand what I did wrong as I am sure I made a mistake somewhere since I am a noob in this area, but still this is obscure to me.

Feel free to ask more information.

Where are you installing/running from?

PyPI (pip, poetry, pipx, etc.)

OCRmyPDF version

16.12.0

What operating system are you working on?

Windows

Operating system details and version

Windows 10 Pro 22H2 (OS Build: 19045.6466)

Simple sanity checks

• Operating system is currently supported by its vendor (not end of life)
• Python version is compatible with OCRmyPDF
• This issue is not about a specific input file

Relevant log output

When in the part where it is running `ocrmypdf` it is outputting the following error meaning it could not find `ghostscript`:

The program 'jbig2' could not be executed or was not found on your
system PATH.  This program is recommended when using the --optimize {2,3} | --jbig2-lossy arguments,
but not required, so we will proceed.  For best results, install the program.

If not already installed, install the Chocolatey package manager. Then use
a command prompt to install the missing package:

Did you install 64-bit Ghostscript? We don't support 32-bit Ghostscript on Windows, or 32-bit on anything for that matter.

We check both the registry and the Program Files folder for Ghostscript.
