Use this script in your .ini file:

if not ISExec ( 0, 0, 0, ExpandConstant('{app}\rebuild.bat'), '', ExpandConstant('{app}'), 'Rebuilding files...',false) then break;

To auto delete the .bat file, simply edit the last line to:
del /f /q rebuild.bat

delete the InjectorMaker.exe too

Sorry for bad english
