If you applied to access to Zemax software through the Zemax Global Academic Program, you will receive an email invitation to set up your Zemax account. If you do not receive this email within 1 day of receiving your license information, please contact email@example.com.
If you are using a campus computer lab or otherwise accessing the software through your university, the License Administrator for your university, likely your professor, will need to add you as an End User to your university's license. Once this is done, you will have access to the Knowledgebase, forums, etc. Students will not be able to create technical support cases.
