[wix-users] Wix Bundle and DetectCondition

[Jacqueline MARECHAL]

Hello Steve,

I need to detect the '.NET Desktop runtime' bundle, not the msi.
The bundle chains 4 msi packages, which all create their own key or value in the registry.
So, you are right, the detect condition is not really the problem, it is easy to detect the bundle. It is sufficient to detect each package.

My real question is how can we check if any more recent '.NET Desktop runtime' bundle is installed.
And I think that it is not feasible without additional code:
- Msi packages of same component for different version do not use common product or upgrade or component codes.
- Values are created in the registry using semantic version, which is not easy to compare
- Keys are also created using version, so that without code able to enumerate sub-keys of a given key, it is not possible to find them, ...
I also thought about work with folders and files, but the target directory can be change at installation :(

But, as you make me realize that it is not a detection problem, I will try to re-evaluate Install Condition in my custom bootstrapper, using specific condition token and variables.

Thank you :)
Jacqueline

You can create a custom action that reads the registry "
SOFTWARE\\dotnet\\Setup\\InstalledVersions\\{bitness}\\sharedfx\\Microsoft.N
ETCore.App"

Where {bitness} is either x86 or x64 

And you will need to know the version you are looking for.
