Change Where NpptoR looks for Rgui.exe

Question

This seems to be a very common problem that has not been solved. When I go to open NpptoR it says it can not find the Rgui.exe file, so I can not run commands from NpptoR in R. I know the problem is that NpptoR is looking in the wrong file directory. My question is, how do I change the file path?

Answer 1

This problem is usually caused b either using an old version of NPPtoR (very likely) or R (less likely). So I recommend you:

1. Deinstall NPPtoR
2. Deinstall R
3. Restart your computer
4. Download and install the latest version of R from here .
5. Download and install the latest version of NPPtoR from here .

If this still fails, click with the Right Mouse Button on the NPPtoR icon in the taskbar and go to settings, where you can change the folder. But if you have done the aforementioned steps, I am confident you will not need to do so.
