How to Call an Exe from an Application Exe using Inshallshield

Hi,

I am new to Installshield can anyone guide me through the steps to achieve the following;

Currently in our project using the SSRS Report Services(ie; an EXE) installed prior to Main Application Installation(ie; an EXE) using installshield.

Now, How to call the SSRS Report Services(ie; an EXE) from the Main Installtion(ie; an EXE) using installshield.

Please assist me to proceed further.

Note:
In short way how to call a Exe (SSRS Report Service) from Main Application - Exe using Installshield. First the SSRS Report Service Exe need to complete the functioanlity and then process the Main Application (EXE).

Thanks.
