My question is: is it possible to set a (environment) variable or a property, only when a feature is selected? (for example in a feautre tree) What would be better, a variable, property…?
And how do I keep or pass the value, so I can check it in an ExePackage or MsiPackage with the InstallCondition?
I hope someone has an idea, because I tried every possible way which came to my mind, an none worked.
thanks!
This blog post describes the problem. One possibility might be to create a reg key component and add that to the feature you are trying to check. Then you could use that component as a test to see whether the feature is being installed. You could also query for that reg key to determine whether the feature was installed later in another installer.
