As my known level of understanding
 

function ISExec

function ISExec (CurComponent:Cardinal; PctOfTotal, ProcessTime:double; ExeName, Parameters, TargetDir, OutputStr:string, Show:boolean):boolean;


Examples:
If not ISExec (0, 0, 0, ExpandConstant ('{tmp} \ precomp.exe'), ExpandConstant ('-r -o "{app} \ data.pak" "{app} \ data.pcf"') , 'Data.pak', false);
Runs the precomp.exe file located in the {tmp} folder with the parameters for extracting data.pcf from {app} into data.pak with the "data.pak" text in the "Extract file:" field in the install window. Console application window is hidden. The progress of the operation is considered based on the test pass and the previous operations performed.


If not ISExec (0, 100, -1, ExpandConstant ('{tmp} \ precomp.exe'), ExpandConstant ('-r -o "{app} \ data.pak" "{app} \ data.pcf"' ), 'Data.pak', false);
The same as the previous example, but the percentages are manual and the progress will be in place before execution, then jump to 100%. The window of the application being launched is also hidden.

Example Are taken from profrager help file.

What is defined by 0, 100, -1

Hey, it's not in english

I think this ISDone Example & Script may help you to understand something and easily creating your own installer using ISDone. Compress files with freearc without external compressor and hook it up with the installer using the example.

Script Edited by Me :D

Ok, I see it's a very beginner script to use for repacking. Let me see how well I can use it
