Why is RSelenium always giving an error when I want to define a Firefox profile

I am using RSelenium and want to set a Firefox profile. So I tried to reproduce the example of the answer to this question. However, no matter what I change I always get the following error. What am I doing wrong?

I already read in the RSelenium manual that for windows systems RTools should be installed when one wants to make a Firefox profile. I did but nothing changed.

The error is the following:

Error in file(tmpfile, "rb") : cannot open the connection
In addition: Warning messages:
1: running command '"zip" -r9Xjq "C:\Users\mariu\AppData\Local\Temp\RtmpQfl3bl\file15c41fc2411d.zip" "C:\Users\mariu\AppData\Local\Temp\RtmpQfl3bl/firefoxprofile/prefs.js" ' had status 127 
2: In file(tmpfile, "rb") :
  cannot open file 'C:\Users\mariu\AppData\Local\Temp\RtmpQfl3bl\file15c41fc2411d.zip': No such file or directory

Sometimes, for some reasons, it is not enough to add Rtools file location to Environmental Variables as was mentioned here. To solve the problem you need to add path within R using folowing code:

writeLines('PATH="${RTOOLS40_HOME}\\usr\\bin;${PATH}"', con = "~/.Renviron")

Then PC needs to be reseted. After that you can check whether path was setted correctly.

Sys.which("make")
## "C:\\rtools40\\usr\\bin\\make.exe

If output of sys.which is "" then something went wrong. By the way the entire procedure has been described here: https://cran.r-project.org/bin/windows/Rtools/.

the problem is that Rselenium cannot create a zip file of your Firefox Profile (error status 127), therefore cannot read it in the next command line.

I resolved following this answer: Create zip file: error running command " " had status 127 .

Do as the link says , shut down R, restart your pc and it should work.

Thanks, Rob
