If Mono v. ≥ 2.8 has been successfully installed and the Linux version of FusionAnalyser has been downloaded, FusionAnalyser can be run by directly calling it from Mono:
Move to the FusionAnalyser folder, open a terminal window and enter the command: mono FusionAnalyser.exe
After a few seconds, the main FusionAnalyser Form will appear.
Do not close the Mono terminal window while FusionAnalyser is running!
