When installing Rtools version 4.2 on Windows 10, I get a pop-up window with the following message at the end of the installation process:
Unable to execute file:
C:\WINDOWS\system32\cmd.exe
CreateProcess failed;code 2.
The system cannot find the file specified.
The only thing I have done previously is to install R (version 4.2.1.).
I fear ignoring this message will lead to issues later on.
