title: how to load a form only at the first time after program is installed
body: <p>My speech recognition project include 2 forms form1 &amp; form2. Form2 is my main form but before loading form2 my program take a variable value from user through form1 and pass it to form2. It means at start my program opens form1 takes value &amp; pass it to form2 then form2 is shown.
  Now my question is how to 
  make form1 load only at programs 1st launch after installation and after 1st launch directly form2 is loaded thereafter?
  means form1 should not be loaded after that..</p>
