hi,
the installation is very easy.
After having downloaded the Civa 1.51 package double click on the autoinstaller and follow the autoinstaller instructions.
Go to your FS main root and check that a folder named CIVA has been created and inside this folder check if the Civac.gau file is present.
Check now the panel .cfg to recognize where the authors have set the INS gauges.Your plane is the payware SSTSIM Concorde and I suppose that every gauge string has been made properly.
That's all.
