[wix-users] How to conditionally remove configuration?

[Hoover, Jacob]

You need to define the property as a secure custom property.

Without detailed logs, now all I am doing is guessing as to why you are having issues. It’s obviously detected the component, and it sees that it wants to uninstall, but something is changing that to Null.

What happens if you define the property as secure, have it named in all upper case, change your Guid on the component to *, and install and uninstall?

Hello Jacob,
thank you for the URL!
With the custom actions from the blog, the PROPERTY CHANGE  of  REMOVE_CONFIG=1  happens earlier than RemoveFile component evaluation.

Unfortunately, the component is evaluated to the Null action and therefore RemoveFile is not called.
      Component: RmConfComponent; Installed: Local;   Request: Absent;   Action: Null

After removing Transient='yes' or using a new GUID the action is still Null.
Could you help me out with this, too?

Thank you,
Markus

Greetings,
sadly, I am unable to use RemoveFile conditionally in the wxs file below.
Is REMOVE_CONFIG not yet present when RemoveFile is scheduled?

Thank you,
Markus
