Run Time Licences

When applications developed in Dyalog are distributed to users or machines other than those for which Developer Licences have been acquired, a Run Time Licence is required. The Run Time Licence is free of charge for stand alone single user applications.

Run Time Licences are not free under the following circumstances:

	When Dyalog is used to implement multi-user applications. Multi-user applications are defined as applications where the same data is shared by or exchanged between two or more users.
	When Dyalog is used as a platform for applications which are distributed outside the organization which holds the Dyalog Developer Licence - whether or not the developer charges a fee for the application, and regardless of whether the application is single or multi user.

Run Time licences are sold for a single user on a single machine. Note that, in situations where APL is used to develop educational tools or applications used in not-for-profit environments, it may be possible for the user to acquire a free Run Time Licence, or for the developer to negotiate an appropriate low cost licence with Dyalog.

Single user Run Time Fees are one time Fees and must be renewed with each new release of Dyalog.

Unix & Linux Run Time

Please note that for Unix and Linux the Run Time Licence includes a Licence to use the MainWin emulation of the Windows GUI interface where required. MainSoft requires a separate contract - approved and signed - with each customer using their product, specifying the number of users.
