No conditions, function just shows a messagebox. I was just testing to see if it would work.
Here it is:
export prototype MyFunction(HWND);
function MyFunction (hMSI)
MessageBox ("InstallShield", INFORMATION);
If put in the execute sequence after AppSearch it is just ignored.
If put in the UI execute sequence after AppSearch log looks like this:
