I have R version 3.6.0 (Running with that) - I also have R 3.5.2 but not running with that.
RStudio version 1.2.1335.
I had an older version of Rstudio (not too old, downloaded in Jan, not sure version num) and when I initially launched that, it gave me the error message:
"Error in tools startdynamichelp(): unable to create socket"
So I tried to download a newer version of RStudio and I just get a screen that says "This site can't be reached" and nothing on the toolbar is clickable.
I have 64 bit OS and 64 bit R.
I also downloaded the new R version 3.6.0 and it works fine, but when I entered help for Rprofile I get this error message again:
starting httpd help server ...Error in startDynamicHelp(TRUE) : unable to create socket
