Dear users and experts,
I installed an OpenMC to my PC. I have a code running in my laptop (i have OpenMC there also), but can not run in in my PC. I am recieving the error below:

If you installed from source, you need to make sure that wherever the openmc executable was installed to is on your PATH environment variable. Note that if you didn’t set the CMAKE_INSTALL_PREFIX variable when running cmake, by default it will install the executable to /usr/local/bin.
