Building from source instead of using the installer needs about 10 GB of tooling (Qt, Visual Studio, Windows SDK).

So what is it?

SVG Explorer Extension is a small add-on for Windows Explorer that makes SVG files show up as thumbnail previews, the same way photos and images normally do. Without it, SVG files appear as blank or generic icons in Windows file browsers. With it installed, you can glance at a folder full of SVGs and see what each one actually looks like. Installation is just a matter of downloading the right installer from the releases page and running it. The main thing to watch out for is matching the installer to your system architecture: download the 64-bit version for a 64-bit Windows system, even though the 32-bit installer will technically run without throwing an error. If thumbnails do not appear after installation, there are a few common fixes. Windows may have thumbnail display turned off in its File Explorer Options settings, in which case you can enable it from the View tab. Alternatively, old cached thumbnails can prevent new ones from appearing, and clearing them through the Disk Cleanup tool usually resolves it. As a last resort, you can force a full refresh by ending the Explorer process, deleting the icon cache file manually, and restarting Explorer. The project has a longer history than most small utilities. It started in 2012 and moved between hosting platforms before landing on GitHub. It went through years of minimal maintenance, then was revived around 2019 when a group of contributors fixed accumulated bugs and set up automated builds. Version 1.0.0 was released on the first day of 2020. For developers who want to build from source, the setup is substantial: the project depends on Qt, Microsoft Visual Studio build tools, the Windows SDK, and an installer tool called Inno Setup. The README estimates roughly 10 GB of tooling to get a full build environment running.
