How to Modify

You might want to modify the installer in order to change its appearance, to embed the installation process inside another installation process, to include additional utilities or to change the installation logic.

In most cases, modifying or abandoning the wrapper will be sufficient.Only in rare cases you will want to change file vJoyInstall.exe.

Wrapper:

If you want to stick to Inno Setup you can just take the current script and make changes in it. The script is quite straight forward. It copies files to their destination, it make some changes in the registry and it has some logic, written in pidgin Pascal, that controls conditional installation.

If you want to move to another wrapper technology - make sure you understand what the current wrapper does - imitate it. This is also true when you want to merge the wrapper into another one.
