Installation on Windows

First, open TF2's custom folder. If you already have a HUD here, remove it or move it somewhere else.

C:\Program Files (x86)\Steam\steamapps\common\Team Fortress 2\tf\custom

Path depends where you've installed Steam. You can check the right path like this.

Back to browser.

Select a theme you want to download and click Download button.

Download screen pops up. First it downloads ToonHUD zip file and then it edits the zip file to add the theme in it.

If the installations stops and/or you get an error at this point, make sure don't have any addons on your browser that could block javascript and/or downloading from Mediafire (like NoScript). Also try to refresh the page (Ctrl + F5) and try again. If you still get an error, change the download source in your ToonHUD account settings.

Browser should return a zip file of your HUD now.

Open the zip file and drag'n'drop the toonhud folder to your custom folder. That's it, open TF2 and enjoy!

When you update your HUD, repeat these steps!
