and I want to know how to deal with this problem, should I install the older cplex and install a new cplex version? or I should register account (I'm a NTU staff) in some where?

Hi

have you tried

?

you seem to use cplex community edition

yeah, I'm trying to use this version and applied one year;

should I uninstall the older version and install the new version?  or just directly install the version and it can overlap the older version?

You may keep both

Hello,

I have installed the academic (student) version of Cplex 12.8. However, I faced the following error when I try to solve my model:

Exception from IBM ILOG CPLEX: CPLEX Error  1016: Promotional version. Problem size limits exceeded.->.

My model contains 1131705 binary variables. However, I think that the academic version of Cplex has no limitation.

How can I fix this error then?

Hi,

this error means you use the free community edition.

Check your path.
