Welcome to KORG!

Goto and GoSub are long-time deprecated - here's an example without:
 Code:
$SystemDrive = Left('%WINDIR%', 2)
$InstRoot = 'S:\Lync\'

$Is64 = IIf(InStr('%PROCESSOR_ARCHITECTURE% %PROCESSOR_ARCHITEW6432%', 'AMD64'), 1, 0)

If InGroup('Lync_Users')
  ; OK to Instal Lync
  ; set the installer based on the platform bitness
  If $Is64           ; running on x64 platform
    $Install = 'setup.exe /configure configuration-en-64.xml'
  Else
    $Install = 'setup.exe /configure configuration-en-86.xml'
  EndIf

  ; run the installer
  'Running: ' $InstRoot $Install @CRLF
  ; Shell $InstRoot + $Install
Else
  'No Lync for you!' @CRLF
EndIf
Installs either version depending on the platform, only if the user is a member of the group. Un-comment the Shell line after testing and verifying that the command to be run is correct. Update the messages appropriately, and add your initialization code (break on, etc..).
