Need help repack my games, im new to this

[GybEMHPj4XAp3Cu]

And where do I add the setup.exe to make a final ISO with DSG for BD 50 or BD 100 and compress it after, because I only see Setup.dll,data1a-01.bin,data2a-01.bin, autoruns.ini & Records.ini in my ISO, where is the setup.exe?

And I don't understand this in the code source of the installers.
#define GameExe "XFRGB\BIN64\XFRGRIDBERD_Launcher.exe"
Do I need to define my game location in %programfiles% which my game is already installed on my pc? or it's where the game gonna get installed ,I suposse it's where the game gonna get installed..

And for the installer, I can't compile it with inno setup? why? I cannot compile any installer???
