Download OpenFK

Select the version of OpenFK you would like to install. If unsure, most Windows 10 PCs and all Windows 11 installations would use the x64 version. If you are installing OpenFK on Linux using Wine, use the x86 version due to compatibility issues related to Adobe Flash Player.

Installation Instructions

To install OpenFK, you need an existing installation of the U.B. Funkeys game along with .NET Framework 4.5. After downloading the ZIP file, simply extract the contents into the RadicaGame folder of your U.B. Funkeys installation directory. When the extraction process has finished, simply run OpenFK instead of UBFunkeys.exe to play.

Flash.OCX Information

OpenFK, like UBFunkeys.exe, still requires Adobe Flash Player to power the game itself. It however does not require an active installation of Adobe Flash Player, only loading an ActiveX plugin file when opened. Due to Adobe's restriction of redistributing Adobe Flash Player files, OpenFK fetches an OCX file from Windows Update. You will get a pop-up when you first launch OpenFK prompting to fetch a Flash.OCX file. Clicking yes will trigger OpenFK's fetching process, which will result in Flash.OCX being downloaded. After the fetching process, OpenFK will restart and launch the U.B. Funkeys game. For Linux users, you will need to use an OCX from Adobe Flash Player 10 due to Wine compatibility issues.
