Download FShell

FShell is provided as binary under the licensing terms described here.

FShell requires a C preprocessor to be installed on your system. On Unix-like systems such a preprocessor will usually be installed already, for Microsoft Windows systems use Visual Studio (the free Visual Studio Express suffices) or please get MinGW or cygwin gcc, which can be installed using MinGW’s installer.

 

If you experience problems running FShell on your platform or require binaries for a platform configuration not listed here, please contact Michael Tautschnig.
