Return error codes for LabVIEW installer

[Tournifreak]

I'm trying to get my LabVIEW installer uploaded to the Microsoft app store. This seems to be a good way to avoid the problem of company policy setups not allowing "random exe files" to be run (as I was told today!)

As far as I can tell, uploading a LabVIEW exe installer to the Microsoft store is no problem. But they also want to know what error codes are produced at exiting the exe installer. I can't find this information anywhere. Has anyone done this before? Any ideas?
