Answer 2

It is probably the issue with the setting with the JAVA_HOME pointer. In case you do not have JDK but JRE, here is you might have to do: Sys.setenv(JAVA_HOME='C:\Program Files\Java\jre1.8.0_161')

Remember to change the numbers after "jre" based on what you have on your computer. Here is a link that explains the difference between JDK and JRE.
