Unable to setup

[Genius-Raptor]

Trying to run setup.py in v7.4 gives the following error:
Traceback (most recent call last): File "D:\Downloads\socli-7.4\setup.py", line 10, in <module> longd = f.read() ^^^^^^^^ File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.12_3.12.1264.0_x64__qbz5n2kfra8p0\Lib\encodings\cp1252.py", line 23, in decode return codecs.charmap_decode(input,self.errors,decoding_table)[0] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ UnicodeDecodeError: 'charmap' codec can't decode byte 0x90 in position 10962: character maps to <undefined>

It seems like a problem with my python installation, but it hasn't caused any problems with other projects. I just want to verify that it is definitely a problem with my installation and not with the script. Any help would be appreciated.
