Warning: NL-files not found during installation

Without hijacking this topic, I also have the same problem with all versions of 8.xx (haven't tried 9.0 yet):
In the setup I have selected the updates for the English and Dutch Windows 7 systems. After installing the updates it seems that some of the Dutch files that should have been downloaded are actually German. The log files show that it cannot find the .nl.exe files of MSSE and IE10 or IE11. After poking around in the installation folders I noticed that the installer downloaded the .de.exe files of these setups! And as you know since you are German, .de is German, .nl is Dutch
I can provide any neccessary log files in the following days.
