You need to have the Gothic II Die Nacht des Raben installed and patched to the latest version (which is v2.6). IF you don't, then do that first, then run the G2aTT-DNdR ETM installer. The installer should autodetect your G2aTT-DNdR installation folder, if not, please press the Browse button and select it by yourself.

The G2aTT-DNdR ETM installer have everything is needed to run it as a Gothic II mod (you don't need to have any Gothic II modkit version to run it, as the installer contains the v2.6a GothicStarter.exe and GothicGame.ini files).

You don't really need to uninstall a previous version of G2DNdR ETM before installing a new one as it overwrites it's own files and uses the same save folder as the last one, so no problems should occur if you're doing it like this. Anyway, if you want to do the things properly, you should uninstall your current version before instaling a new one, to avoid any potential problems.

Also, regarding the installation of Gothic II's addon Die Nacht des Raben over the english version of Gothic II, you could do it thanks to Piranha Bytes! All you need to do is to get Gothic II's german v1.30 patch, then launch it in the extract only mode (via a Run command line like this: Gothic2_130_de.exe /X ) and you can extract from it only the files you need (ie the Gothic2.exe v1.30 file). Replace the Gothic II english version's one with this new one, then install Gothic II addon's Die Nacht des Raben as usual.

UNINSTALLING

Just run the G2aTT-G2TNoTR Uninstall.exe from your main Gothic II installation folder. That little program will do everything for you!

RUNNING

As it is provided as a mod, the G2aTT-DNdR ETM doesn't harm in any way your original german Gothic II Die Nacht des Raben installation. All you need to do start the game is to run the GothicStarter.exe program from the System subfolder of your main Gothic II Die Nacht des Raben installation folder. Once started, you can choose if you want to run the original german Gothic II Die Nacht des Raben game, G2aTT-DNdR ETM or any other Gothic II mod you have installed.
