Inno Setup and Vb.net project

Hi all

Here is my problem
I have developped the code below (using inno installer)
What it does it checks if the .net framework is installed.If not, it prompts the user to download it and install it. This is all good
Now, my problem is that when the .net is present and installed, i would like to run a vb.net apllication (here ABC.exe). This file is in the same folder as the .iss file. Problem: i dont know how to do it ???

can anyone help ?

Thanks
