Frequently asked questions
Do you offer a no-cost trial for IBM ILOG CPLEX Optimization Studio?
Yes, we offer IBM ILOG CPLEX Optimization no-cost edition. You can register to download it at the link below. The no-cost edition is restricted to problems up to 1,000 variables and 1,000 constraints. A time-limited trial without restrictions on problem size is available upon request by contacting an IBM sales representative.
Do you have an unlimited version of IBM ILOG CPLEX Optimization Studio for students and faculty members?
Beyond the commercial version, IBM runs the IBM Academic Initiative where students and faculty members have access to the product at no cost. Our academic entry is without functional or model size limitations, and you must register to check your eligibility. If the program accepts you, then you will get an email notification with download instructions.
How does billing work for the subscription license?
The CPLEX subscription can be purchased as a monthly or annual subscription and is charged at the beginning of the billing period. You will be automatically billed on a periodic basis, according to the terms of your subscription.
How do I cancel my subscription license?
Before you reach the next month of your subscription offering, contact us to cancel your automatic renewal.
How can I share my CPLEX subscription within my team?
A single subscription may include one or more users, and each user receives a personal key to unlock the software. Each member of your team who uses IBM ILOG CPLEX Optimization Studio needs to have his/her own key. Users can be managed from My Products and Services. When you remove a user from the subscription, his or her key becomes inactive. When you add a user to the subscription, he or she receives a key.
Do I have to be online to use the subscription license?
Each day when the first "solve" happens, the software goes to check eligibility to use the product unlimited. However, after at least one check, the user can be offline for 14 days before the product goes back to the limited mode. If the user connects and eligibility is checked before the end of the 14th day, then the user again could be offline for another 14 days.
Is support included for your subscription offering and other licensing options?
Yes, support is included for the purchased months for subscription and 12 months for the other licensing options.
What are the software requirements for the IBM ILOG CPLEX Optimization Studio subscription?
