2019_Error: Unable to establish connection with R session

Hi everyone! I have been perfectly working with R. However, a few days ago start to giving me the message "Unable to establish connection with R session" Please, can someone help me by solving this problem?


Hello! I downloaded RStudio for the first time yesterday and I'm having this same issue. Unfortunately I don't have a solution yet, but I guess it's not just a me problem?

For what it's worth I'm running Windows 10.

Have you also installed R? Have in mind that RStudio is an IDE for the R programming language.

Yes, I have also installed R. I tried to edit the RStudio build settings, but it told me I need to be in a project to do that, and when I tried to create a project it threw the original error.

Yes! We supposed to have R installed otherwise is not going to work!

Hi all,

I just figured it out how to solve the problem, here the steps of what I did:

  1. Uninstalls the R file and R Studio
  2. Delete folder from C program folder and delete the setup files from the place where do you save tem.
  3. Install R-3.4.2 & RStudio desktop 1.1.463

I hope it will help you to!
