Alright I was able to figure the issue I was using incorrect integration pack correct one for desktop 10 and above is 2nd last link from Download page one which says (Desktop Installer (version 10 and above)). Also R version needed to be R.3.2.5..I was able to test clustering and pairwise correlation metrics in Desktop.
I'm still looking for steps required for setting up R on MSTR Cloud environment.
