Hi Sarah, it looks like the problem goes into your PATH environment variables. Did you try opening R and Matlab in your terminal? Maybe check the path by 'which' or 'where' (windows). We can also chat per skype 'Janine E' if you can not manage opening the R/Matlab instances. Best, Janine

This is the same issue of the system not finding the R executable. If so, try to add the R path to your system environmental variable, or define the R path in the Rinit function as second input argument Rinit([],'C:\Program Files\R\R-4.1.0\bin\R.exe')

Setting the R path solved the problem on both machines
