Installation of R is stuck on defining Path to R Home

Dear Knimers

I’m trying to get under Windows10 in Knime 4.3.0 R up and running again. I’ve been through this ordeal before using Windows7 and Knime 4.1.3 where I got it working by using all the great tips given in this topic:

Install R alongside KNIME on Windows and MacOS

Over the last months I have collected a few entries about the installation of R alongside KNIME that contain some maybe useful hints how to overcome certain obstacles while installing them. I want to bring them together here. (If you are looking for a basic guide about how to install R in the first place you might look here or here). A few maybe unnecessary remarks upfront. Yes it takes some effort to get KNIME and R up and running but in the end you will be rewarded with the whole world of pos…

I’m using Anaconda to keep track of the environments (which does work for Python happily; the py3-knime environment is created and working). The RStudio environment which is created by Anaconda gives me R version 3.6.1.
I’ve installed the version 1.8-6 of RServe using RStudio (I tried the binaries and an own compiled version; both give the same error in the end) and installed Cairo.

Issue with KNIME R version

I ran Rserve() function in RStudio and after that KNIME changed R Home directory.

RServe starts without problems, but it does not make any difference, the error remains.

Does anyone have a clue what could be the real issue here?

The problem got solved. It had to do with authorisations my employer applies to our WIndows-10 pc’s. I installed R and RStudio not through Anaconda anymore, added Rserve again (latest version 1.8-7) and now it’s working as before.

@ScottF indeed very glad
It does make things easier for my colleagues when they migrate too.
