Hello, Following [this instruction](https://docs.knime.com/2019-12/r_installation_guide/index.html#_windows) to integrate R and Knime, I could not install Rserve on the local R instance. I am trying to integrate Knime and R on windows 10. I copied the error as follows: "C:/rtools40/mingw32/bin/“gcc -I"C:/PROGRA~1/R/R-4.1.2/include” -DNDEBUG -DRSERVE\_PKG -DWin32 -I. -Iinclude -Iinclude/Win32 -O2 -Wall -std=gnu99 -mfpmath=sse -msse2 -mstackrealign -c oc.c -o oc.o oc.c:11:10: fatal error: openssl/rand.h: No such file or directory #include \ ^ ~~~~~~~~~~~~~~~ compilation terminated. make: \*\*\* [C:/PROGRA~1/R/R-4.1.2/etc/i386/Makeconf:238: oc.o] Error 1 ERROR: compilation failed for package ‘Rserve’ - removing ‘C:/-----/Rpackages/Rserve’ Warning in install.packages : installation of package ‘Rserve’ had non-zero exit status ---

@ehsanT what you should do is make sure RServe does run under R / Studio alone and will be started when library(“Rserve”) is called. Then you could tray the integration into KNIME. In order to do a fresh installation you might try these steps if the ones from the R integration guide would not work. The latest Version 1.8-10 should be available as a Windows binary so there would be no need to compile: [https://CRAN.R-project.org/package=Rserve](https://cran.r-project.org/package=Rserve) For Windows: ```auto install.packages("Rserve", repos = "https://cran.r-project.org", type="win.binary") ``` If this is not successful you could try and do a installation via the [installr package](https://CRAN.R-project.org/package=installr) like this: ```auto # install.packages("installr") library(installr) install.packages.zip("https://cran.r-project.org/bin/windows/contrib/4.1/Rserve_1.8-10.zip") ``` or: ```auto install.packages("https://cran.r-project.org/bin/windows/contrib/4.1/Rserve_1.8-10.zip", repos = NULL, type ="win.binary") ``` You might want to check the latest binary version on the [Rserve website](https://cran.r-project.org/package=Rserve): ![image](https://forum-cdn.knime.com/uploads/default/original/3X/2/1/21b6ddfd36d11142030cf0b1fdd3088cb9454d42.png) * * * The same thing for MacOS would look like this: ```auto install.packages("Rserve", repos = "https://cran.r-project.org", type="mac.binary") ``` Or you could do with the specific package version: ```auto install.packages("https://cran.r-project.org/bin/macosx/contrib/4.1/Rserve_1.8-10.tgz", repos = NULL, type ="mac.binary") ``` Besides the [official guide to R and KNIME integration](https://docs.knime.com/latest/r_installation_guide/index.html#_introduction) I try to keep track of several ways and quirks around KNIME and R/RStudio here: > **[A meta collection and article about R and KNIME – mlauber71](https://hub.knime.com/mlauber71/spaces/Public/latest/_r_installation_on_knime_collection~tj5tS_6gYvqOSPlk)** > > A meta collection and article about R and KNIME R gives you the power to do a lot of great things combined with KNIME but to get R and KNIME together up and ru… You could check the version and packages of your R installation in KNIME here: > **[check version of R packages in KNIME – mlauber71](https://hub.knime.com/mlauber71/spaces/Public/latest/kn_example_r_check_version_of_package~annQfxz-Mrtn2BNm)** > > demonstrates how to check the versions of every R package.

Thank you @mlauber71 . It was fixed by running the first line of code. 👌 ---
