I found the source of the problem. 2 includes in front at the start of the Marlin file. I commented them out then it compiled. However I still get two error messages during compiling one for Sd2card.cpp and other for Stepper.cpp library included .. However it compiles none the less?? I've also made some changes to do Auto leveling and that also compiled with Arduino version 1.8.8. I haven't started debugging it with the hardware yet.
Also after I deleted Arudiono IDE I tried to follow:
Delete files in:
C:\Users<your directory>\AppData\Local\temp
C:\Users<your name>\AppData\Local\Arduino15
following "Window Explorer: View > check the box next to "Hidden Items"." but did not see that selection.
