Eyeon:Script/Reference/Applications/eyeonScript/Installing
From VFXPedia
eyeonScript requires four files to operate, the eyeonScript.exe program, eyeonScript.dll, lua5.1.dll and iup2.5.dll. These files can be found in the main Fusion folder (C:\Program Files\Fusion for a default installation).
If you are installing eyeonScript for use on a computer without a local installation of Fusion, you can locate eyeonScript.exe on the install CD rom in the Setup\Script folder. This application does not require special installation before it can be used, simply copy the files into the desired directory on the workstation.
We recommend that you copy eyeonScript.exe into a directory in your executable path (like Windows\System32) or place the folder where it resides into the PATH environment variable. This will allow you to run eyeonScript.exe without requiring you to type the full path to the application each time you use it.
Registering the .eyeonscript Extension
Running eyeonScript.exe with the '-r' argument will cause it to register the .eyeonScript extension as an executable file type. This associates files with this extension with the eyeonScript.exe program so that you are no longer required to type 'eyeonScript scriptname'. Instead you can simply double click on a script file from within the file explorer, or type the scriptname at the command prompt.
