I recently downloaded F1 Via Gog downloader. I right click > launch installer but nothing happens.

(Im running wXP)

Do you have the new downloader installed? I started having problems with it and contacted support and they told me to uninstall the downloader and get the new one. I've only used it once since then, but it worked perfectly. Also, you can open the installer from the GOG folder on your computer. Just run a search for GOG or Fallout and you should find it no problem. Hope this helped.
