ImportError: You need to install Visual C++ Redist

On Windows, one of selenium-wire's compiled dependencies needs the Visual C++ Redistributable runtime and it is not on the machine. Download the latest x86 AND x64 redistributables from Microsoft, install both, then re-run. This is a system prerequisite, not a Python package problem, so no pip command fixes it.

The error

ImportError: You need to install Visual C++ Redist

Fix it

1. Install the Visual C++ Redistributables (both architectures)

Download from the official Microsoft support page for the latest Visual C++ downloads and install the x86 and the x64 redistributables. Expected: both installers complete successfully. A reboot is sometimes needed before the DLLs register.

1. Re-run your script

python -c "from seleniumwire import webdriver; print('ok')"

Expected: prints ok with no ImportError.

1. If it persists, refresh the environment

Delete and recreate the virtualenv (the issue thread notes stale env folders keep the failure), then reinstall requirements. Expected: the import works in the clean env once the redist is present.

When this applies

• the ImportError literally tells you to install Visual C++ Redist
• you are on Windows running an app that bundles selenium-wire (e.g. TwitchDropsMiner)
• a fresh Windows machine or a new user account

When it does NOT apply

• macOS/Linux never produce this error
• No module named 'seleniumwire' is the missing install
• DLL load failed without this message is a different binary problem

Compatibility

Windows-only. The compiled dependency needing the CRT ships with selenium-wire's dependency tree on Windows.

Variant phrasings

ImportError: You need to install Visual C++ Redist (x86 and x64): [url]

The full message with the Microsoft download link. Same fix: install both architectures.

Why it happens

Some of selenium-wire's Windows dependencies ship compiled extension modules linked against the Visual C++ runtime. That runtime is not part of Windows itself; most dev machines have it incidentally (installed by other software), but clean machines do not, so the import fails with this explicit message instead of a cryptic DLL error.

Edge cases

• Install BOTH x86 and x64. Installing only the one matching your OS is the most common reason the fix appears not to work.
• Portable/no-install Python distributions do not register the CRT for you. The redist install is still required.
• If corporate policy blocks the installer, you cannot work around this from pip. It needs admin or the IT-packaged redist.
