RegRead and Software installation Help

[Bac83]

Hi

Im new to AutoIT and have been reading through various posts to answer my question

Im started writing my script, Which basically looks to see if a version of software is installed, if it is the script should exit, if not it should execute an .exe

At the moment my script isnt working

if RegRead "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{147BCE03-C0F1-4C9F-8157-6A89B6D2D973}" Then
    Exit
Else 
    Run("Apps\HITS\SetupVse.exe")
    Endif
Exit

Any help would be great! Cheers!

I think ive solved it already with

if RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{147BCE03-C0F1-4C9F-8157-6A89B6D2D973}","Version=8070000") Then
    Exit
Else 
    Run("Apps\HITS\SetupVse.exe /q")
    Endif
Exit
