I am pretty new to Fluka and Flair. I installed Fluka and Flair on my Window desktop by following all the instructions given on the webpage. While I was running an example using Flair I got an error about the gfortran version (please see attached screenshot). My question is do I need to re-install everything from scratch by installing the 7th version of gfortran or is there any other way for resolving the issue? Also, I am not able to locate 7th version of gfortran on the internet. Please help me in resolving the issue.
