Yesterday I removed R2.11 from my system (Win7, 64bit), since I´m working on R2.13.

Since then i get an error message:

Answer 1

• In RStudio type .LibPaths()
• This will give you an path in you windows system where your library’s are located

• Go there and delete rJava. If it is being used by applications of Java, kill all Java programs in the Task Manager.

• Go to computer and properties, click on change environment variables

• Edit JAVA_HOME and all Java related paths to the path where your newest installation of Java is located and save.
