title: Getting an error : Missing Required Command Line Arguments: -ism <ISM file>
body: <p>I'm building an installer using script file. I'm executing following command :</p>
  
  <pre><code>C:\windows\system32\cscript.exe "%WSR%\InstallShield\BuildInstalls.vbs" -ism "C:\InstallShield\Windows\xyz.ism" -verbose Build -version 1.1.1 -skipcopy -Platform Win32 -web
  </code></pre>
  
  <p>But I'm getting following error :</p>
  
  <blockquote>
    <p>Microsoft (R) Windows Script Host Version 5.8 Copyright (C) Microsoft
    Corporation. All rights reserved.</p>
    
    <p>Setup Output Log File:
    InstallShield\BuildInstalls.vbs_3_25_2016_13_3.out<br>
    InstallBuild ERROR:
    Missing Required Command Line Arguments:  -ism </p>
  </blockquote>
  
  <p>ISM file is also present at proper location and all parameters are correct. But still I'm getting this error. So where I'm doing the mistake ?</p>
