Notepad++ running from a locked usb-stick

I would like to run Notepad++Portable from a non-writeable media (I am using a lockable usb-stick).

In the readme.txt (to be found in Notepad++Portable\other\Notepad++PortableSource) I have found some hints and a Notepad++Portable.ini - file.

As described in the readme.txt the Notepad++Portable.ini looks like:

[Notepad++Portable]
Notepad++Directory=App\Notepad++
SettingsDirectory=Data\settings
Notepad++Executable=Notepad++.exe
AdditionalParameters=
DisableSplashScree=false

And as described in the readme.txt, the main switch to make Notepad++Portable running from a non-writeable media should be the SkipBackups entry, but that entry is not included in the example above.

But what is the correct syntax for SkipBackups ?

I have tried that:

[Notepad++Portable]
Notepad++Directory=App\Notepad++
SettingsDirectory=Data\settings
Notepad++Executable=Notepad++.exe
AdditionalParameters=
DisableSplashScreen=false
SkipBackups=true

Unfortunately that does not work !

Notepad starts with 2 error-messages

Load config.xml failed

and

Load stylers.xml failed

and the running Notepad++ looks rather different (and is not in my localization german).

Can anyone give me a hint how the Notepad++Portable.ini has to be customized for running from a non-writeable media?
