Avoid functional dependency on TargetPanel - allow installers without TargetPanel
There have been reported several functional dependencies on the execution of TargetPanel. Skipping TargetPanel in an installation seems to result in several problems, functional and hanging installers.
The requirement to have a TargetPanel should be generally removed.
I created this task for the implementer to see all at one place, although installers without a TargetPanel is still a rare case, IMHO.
