@Esto100nec1, please tell me, does the program you use to create the installer recognize the folder where the game is installed?

Well, if you have programming skills, you can write a script or look for an existing one, add it, and the installer will be able to find the game folder for installation.
The installer in the screenshot doesn't have this function. It's just a regular installer. It only remembers the last path where the program was installed from this installer. But you can choose the game folder yourself, and it will install what needs to be installed where it needs to be installed, depending on the checkboxes selected in the installer.
