If you have registered your copy of Dyalog or have a commercial licence then you will have been sent a Dyalog serial number; this serial number is individual to you and corresponds to the type of licence that you are entitled to use.
On Microsoft Windows, you can enter your Dyalog serial number during or after the installation process; on all other platforms the Dyalog serial number should be entered after installation.
Instructions on how to enter your Dyalog serial number are included in the following platform-specific documents:
If you already have a registered or commercial version of Dyalog then you will already have a Dyalog serial number – if cannot remember it, then please contact sales@dyalog.com.
Using or entering a serial number other than the one issued to you is not permitted. Transferring the serial number to anyone else is not permitted.
