This site is about how to run Geany on Windows and what is different from other platforms.
To run Geany under Windows you may need to install the GTK+ runtime libraries, depending how you installed Geany. If you use the official full installer, a recent GTK+ runtime is included and you don't need any additional software.
If not using the full installer, you need to install a GTK+ runtime environment. The best way is to use the MSYS2 project which provides all necessary dependencies to build and run Geany on Windows coupled with a comfortable package manager.
Information on how to build Geany from source yourself on Windows can be found on Build Geany on Windows (using MSYS2)
(The Geany Windows executable can be downloaded from the Geany website.)
