It may be worth asking the IT department at work, just in case there is
a system to prevent unauthorised programs from running that interferes
with Rtools.

Are you comfortable using the command line? If you create a hello.c
file with the following contents:

#include <stdio.h>
int main(void) { printf("Hello world!\n"); }

...and then place it into %USERPROFILE% (C:/Users/Christophe Bousquet),
start "Rtools43 bash" from the Start menu and try the following command

export PATH=/x86_64-w64-mingw32.static.posix/bin:$PATH
gcc -o hello.exe hello.c

Does it say hello to you?

Best regards,
