Windows:

InstallFril4982.exe is an uncompressed installer for Windows. It creates two versions - a 32 bit console application, which runs in a DOS-style window, and a simple windows version of Fril with basic cut/paste facilities.
You will need to restart your computer, as Fril needs environment variables to be set by autoexec.bat.

Linux:

linuxfril.tgz is a Linux version, stored as a tar archive, compressed with gzip. Use

tar xzvf linuxfril.tgz

to extract Fril.
In case of compatibility problems with libraries, try linuxfrilStat.tgz which contains a statically linked version of Fril (takes more space).

The 4.981 versions have a minor fix to built-in predicates and (more importantly) contain libFril.so in the library folder, allowing Fril to be embedded in a C program.
