[alinganpatra20004]

My code is working in local environment of windows10 with venv on Python 3.10.11. However, on deploying in Windows Server 2022 with Apache2 webserver with venv on Python 3.11.3 getting following error. I have trying upgrading, installing binary. Till now issue is not resolved. Can anyone help in getting the issue resolved?

Tried to update the setup tools but did not worked

python -m pip install --upgrade pip setuptools

Tried to downgrade the Python to 3.10 but did not worked.

installing Rust doesn't work.

Tried installing binary for cryptography but did not worked.

python -m pip install cryptography --only-binary cryptography

I'm not familiar with this error, however some Googling suggests other people resolved similar errors by installing https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

@alex , Thanks for suggesting this approach. However, the issue has not been resolved even after installing the latest Microsoft Visual C++ version, 2015-2022. I am getting the same error.
