Hi, I work at a University, we have a number of students wanting to use Fortran; specifically older versions (2013) due to compatibility issues with other software. When they register and get their license codes, Fortran doesn't accept the license keys. The message returned is always "Activation rights do not allow this software to be installed. This could be due to expired subscription or incompatible serial number."
I see there are a number of the same problem in your forums and site, but have yet to see a solution. These are freshly requested keys, not ones that have aged, also the software was downloaded from the Intel site immediately before trying the registration.
