I removed the program from the computer , installed it again and it still shows the mistake. It is also strange, that I chose "english" as installlanguage, but the program is in german (my OS is in german). Pls help, because otherwise i cannot solve any problems with R. Using Win7 and R version 2.15.0 (2012-03-30).
