Wise installation studio 9.02 product guid

Hi there,

I just wanted to ask if Wise installation studio is using some guids for products.. because when I was looking into HKCU\Software\Microsoft\Windows\CurrentVersion\Uninstall our product has only text key... it wasn`t guid like: {3F402EA3-E356-460A-99FE-2C2831A37111}

I`m asking for that because it looks like better option to check the guid, if I want to check if soft is installed... like some text in Registry which is more likely to change...

Thanks Dusan
