Re: [WiX-devs] Guid="*" Algorithm

Correct where “goes” means “installs to”.

Subject: Re: [WiX-devs] Guid="*" Algorithm

Hi,

1. I found the implementation at `Uuid.NewUuid` in `src\tools\wix\Uuid.cs`.
2. Seems to be derived from the full KeyPath of the component. So as long as everything goes to the same place the GUID will not change.

Hello All,

I was unable to find the algorithm in the code for the generation of Guids that have a value of *. I have two questions.

1. Where is this algorithm?

2. Is intended to be stable across upgrade codes? I.e. if a user decided to split an application installer that universally uses Guid="*" in half because it is really two products, can they still use Guid="*" in both new installers or will they have to hard code the Guids to prevent component rule violations?


Thanks & Regards,
