Control Click works for the first time and doesn't work after that at all

Hi,

I am trying to automate the installation of desktop application but I am unable to do so at the very first step as I am unable to click the "Next" button. Please help. Below is the code I am using:

RunWait('msiexec /i "C:\Users\s\Desktop\Auto IT\Scripts\Installer.msi"')

WinWait('Setup')
WinActivate('Setup')

Do
    $Start = ControlGetHandle('Setup','Next','[CLASS:Button; INSTANCE:1]')
    Sleep(1000)
Until $Start
ControlClick('Setup','', $Start)

@salungh if it is an MSI, why not install it silently, rather than the messier route of automating the GUI? Something like:

RunWait('msiexec /i "C:\Users\s\Desktop\Auto IT\Scripts\Installer.msi" /qn')
