Ich hoffe du kannst english ist aber nicht schwierig
Either:
Install race v1.1.1 first and then without deinstalling 1.1.1 install 1.1.2 in the exact same folder as 1.1.1.
Or:
That was the easier way; Alternativly you can do:
1. rename the "editor" folder to "map_editor"
2. copy the models folder from MTA San Andreas\mods\map_editor\ to MTA San Andreas\mods\race\
3. create \mods\map_editor\maps#
