[wix-users] Checking for Product A before installing Product B

[Swatantra Yadav]

Hello All,

I have a requirement to install Product B only if Product A is not installed. Otherwise Product B installation should error. Does the below check look correct? I am checking for existence of a component that would be present if Product A is already installed. The check must only run at installation and not run on uninstall or update.

Thanks,
Swat
