I thought IBM was offering fully functional version of CPLEX 12.8 through the academic initiative. Alas, this is the error I am getting when solving a model which I was earlier able to solve with version 12.6:

Error: CPLEX Error  1016: Promotional version. Problem size limits exceeded

The sad part is that no other version is now available besides 12.8 through the academic initiative link!! Otherwise, I will try out version 12.7.

My reason for moving to version 12.8 from version 12.5 was to compile my code with

-stdlib=libc++ instead of 

-stdlib=stdlibc++

Note: I work on MACOSX

Please help!

Hi Sanchit,

Did you get your installer from this page https://ibm.onthehub.com/WebStore/ProductSearchOfferingList.aspx?srch=ilog+cplex and not from the Free trial page ? All installers thet you get from the former are not limited in terms of problem size.
