I am student at the University of Regina in Canada and given a licence because of my student status. I type my codes in Visual Studio and the Intel Fortran compiler for execution. I notice however I am not able to use the Fortran Compiler unless I am connected to the Internet and in particular, my school's network. Is this the case?
I see the two following errors when I am compiling:
Error Error A license for Comp-FW is not available (-9,57).
Error error #10052: could not checkout FLEXlm license
That is a characteristic of the floating license, which requires token checkout from your organization's license server, so as to enforce the limit on number of simultaneous invocations. You could buy an individual student license which would not be subject to this restriction.
As Tim says, a floating license would cause this behavior. It could be that your school gave you a serial number for a floating license rather than a classroom or individual student license. Please talk to your instructor or school IT department to see if that is the case. We do offer free student licenses that don't require a network connection to be active during use.
