# 2.1. Windows

This section describes how to install Groonga on Windows. You can install Groonga by extracting a zip package.

We distribute both 32-bit and 64-bit packages but we strongly recommend a 64-bit package for server. You should use a 32-bit package just only for tests or development. You will encounter an out of memory error with a 32-bit package even if you just process medium size data.

## 2.1.1. zip

For 32-bit environment, download x86 zip archive from packages.groonga.org:

> - https://packages.groonga.org/windows/groonga/groonga-latest-x86-vs2019-with-vcruntime.zip

If we don’t need Microsoft Visual C++ Runtime Library, we download from the following URL:

> - https://packages.groonga.org/windows/groonga/groonga-latest-x86-vs2019.zip

Then extract it.

For 64-bit environment, download x64 zip archive from packages.groonga.org:

> - https://packages.groonga.org/windows/groonga/groonga-latest-x64-vs2019-with-vcruntime.zip

If we don’t need Microsoft Visual C++ Runtime Library, we download from the following URL:

> - https://packages.groonga.org/windows/groonga/groonga-latest-x64-vs2019.zip

Then extract it.

You can find groonga executable file in `bin` folder.

## 2.1.2. Build from source

You can build Groonga from the source with CMake.
