The most common question we receive is how to install the GAMS license file correctly. If you have purchased GAMS, then you will have received an email with the license information. If you just want to give GAMS a try, you have to create a free demo license for yourself on our download page . You will then receive an automated email with your demo license information. Once you have that information, you can follow the steps shown in the video below:
In case of other technical problems please contact the GAMS support at email@example.com .
To speed up the process, please provide the following information:
Our e-mail system can handle attachments up to a size of 20MB and does not accept executable files (such as files ending in .exe, bat, ps, or cmd), even if they are sent in a zipped (.zip, .tar, .tgz, .taz, .z, .gz) format. Any message of this type sent to us will be bounced back you. Adding an underscore to the file attachment (e.g. file.zip_) will help.
If you want to send us a larger file you can use our upload facility. Make sure to send an accompanying email to firstname.lastname@example.org to let us know what you sent.
In general we will get back to you within 8 business hours. In case you do not receive a reply within 16 business hours then please see our contact page for alternative ways of contacting us.
