title: WizardForm.DirEdit.Text not updating properly. Inno setup
body: <p>I am trying to set the path in the 'choose install directory' form using INNO setup. Here is my code</p>
  
  <pre><code>procedure CurPageChanged(pageID: Integer);                                                   
  var
    sInstallDir: String;  
  begin                                                                   
  
    // Default install dir is the IIS install path
    if (pageID = wpSelectDir) then begin
      sInstallDir := GetIISInstallPath + '\MyFolder';
      Log('GetIISInstallPath: '+ GetIISInstallPath);
      Log('sInstallDir: ' + sInstallDir);
      WizardForm.DirEdit.Text := sInstallDir;    
    end;  
  end;
  </code></pre>
  
  <p>The problem I am having is that 'GetIISInstallPath' returns me 'c:\inetpub\wwwroot and that is what I see in the WizardForm. It seems to not add the MyFolder bit.
  I printed out the involved variables and they all have the correct value.</p>
  
  <p>sInstallDir shows up as 'C:\inetpub\wwwroot\MyFolder' but it does not show in the text field. It shows (as mentioned) only 'C:\inetpub\wwwroot'.</p>
  
  <p>Please advise.</p>
  
  <p>Thank You</p>
