Thats good to know. And also kind-a-strange and somehow misleading (for
me anyway) as the following works during uninstallation [Set in the
ControlScript -> TargetDirectoryPageCallback]:

* installer.performOperation("Execute",
["@HomeDir@\\AppData\\Local\\Oliver Niebuhr\\ProcessExplorer\\procexp.exe"])

The SysInternals Process Explorer starts and the Uninstaller waits until
I close it - as it should.

It never occured to me that I should need to add the "UNDOEXECUTE"
Parameter. I will try that. Also I am currently reading the rest of the
QtIFW Issues - and will definitely add more Feature Requests and BR
later this week. That operations like "Delete" can only handle 1 Single
File is nonsense IMHO. But maybe there was a good reason for that
Decision back then. Or some kind of Limitation.
