Single Computer License

Dimension can be licensed on a per-computer basis.

Concurrent License

Concurrent licenses are dynamically allocated to PCs when eTakeoff starts and released when eTakeoff closes.  This is known as checking out a license and checking in a license. The license can be installed on as many PCs as you want, but can only be checked out for as many concurrent licenses as you have purchased.

Basic Free License

The free version of Dimension can be placed on any computer used to review all information created with the purchased versions.
