title: Installshield Run EXE only during install
body: <p>I have another question regarding exe's and custom actions within Installshield.</p>
  
  <p>I currently have a set of custom actions which launch executables in silent mode..</p>
  
  <p>In the return process, it is set for Synchronous(Check exit code) mode, and it is set for a Deferred Execution in System Context.</p>
  
  <p>My question is the following:</p>
  
  <p>When I install my application, it is fine. It runs through the installers and installs the prerequisites. My problem is when I want to uninstall the application from the machine, because it runs through the same installers again (and trys to install them again, even though we are uninstalling).</p>
  
  <p>I looked all around, and cannot find a good work-around for this.</p>
  
  <p>Anyone have experience with this and know of a method of getting the installs to only run when the installer runs and not when uninstalling?</p>
  
  <p>Much Appreciated...</p>
  
  <p>Thanks
  -Kyle</p>
