Hey @agjell note that installing and running displaycal on windows is atm not truly supported. You would have to make changes to several files just in order to make displaycal start on windows and even then you would not be able to perform a calibration.

Independently of that, the error comes from the missing package pywin32. This can be solved by pip install pywin32

[agjell]

Ok, noted :)
Pywin32 was installed, though. So the error must come from elsewhere.

[q1ngyang]

I have encountered the same issue as well, ensuring that pywin32 is installed.

pywin32 would have to be specified in project.toml - however that will break non-windows builds. As such, the setup.py has to be modified to add build system dependencies dynamically as per:
https://setuptools.pypa.io/en/latest/build_meta.html#dynamic-build-dependencies-and-other-build-meta-tweaks

[AstralStorm]

Fixed in my pull request.

[515orestis]

Fixed in my pull request.

the commit seems to work. clone the project from dev branch
but when i try to start DisplayCAL from powershell this text instead for the appUi

#!C:\Python312\python.exe

-- coding: utf-8 --

from DisplayCAL.main import main

main()

[AstralStorm]

The commit does not fix the executable creation and the shell script is a Bash script, not PowerShell.

You can run DisplayCal in the virtualenv after installing for the moment, using:
python ./DisplayCal.pyw
from the dist tarball
Likewise works for the other executables.

or in the source code directory
python ./main.py
for the uncompiled version.

Fixed with #312
