title: How can I modify the text in the MUI_WELCOME_PAGE when using MUI2 for NSIS?
body: <p>I want to add a label displaying the full version-string in the welcome screen in the installer I am creating using NSIS with MUI2.</p>
  
  <p>I have searched for info on how to do this, but only found references to using MUI_INSTALLOPTIONS* which I found ws deprecated for MUI2. Another one referred to the newer versions using INSTALLOPTIONS* with the same options, but I could not get it working. I finally also found a reference to using nsDialogs for this - which is what I am using for my custom pages. However - I found no reference or samples on how to change any of the existing pages that comes with MUI2.nsh.</p>
  
  <p>I found a way to change the MUI_HEADERTEXT, but that doesn't affect the welcome-screen. I wish there was a way to also change the welcometext. Maybe using MUI_WELCOMETITLE and MUI_WELCOMEBODY or similar.</p>
