With Paquet Builder, you can configure your Self-Extracting installer package to run multiple EXE files after extraction (sequentially: each EXE program is run and we wait for its end before running next one). The following guide shows you the steps to do so.
In your current project, we are going to add the EXE files you want to compress into the installer package and run after extraction.
In our tutorial, we choose 3 EXE files. Note that you can add files with drag and drop!
In our tutorial, this is HelloA.exe. In Paquet Builder, %DESTPATH% is a reference to the destination folder where files are unpacked to.
This checkbox tells Paquet Builder that the package should wait until the EXE has finished. It's an important step.
Edit the two new actions to change the Filename property to respective remaining EXE files (HelloB.exe and HelloC.exe in our case).
As configured, the Self-Extracting installer will unpack files, and then run HelloA.exe, wait for its end, then run HelloB.exe, wait for its end and so on.
