Download the latest full version of dBSea (requires server license, HASP key or trial license): dBSea 2.4.11

Version 2.4.0 introduced support for server-managed licenses, which do not require a HASP key. Please contact your distributor for details. Existing HASP keys and soft licenses will continue to work with this version - existing customers do not need to make any changes at this time.

To use dBSea 2.x with an existing HASP key, we will need to upgrade your key details. You can generate a C2V file with Tools -> Generate C2V. Contact dBSea with your C2V so we can update you for version 2.x.

Or try dBSea Basic 2.3.6 It's free to use. It needs no HASP key or trial license, but it's restricted to simple logarithmic solvers that do not account for environmental variables.

Please contact your local distributor to request a 30 day trial and pricing information for your region, or for a 32 bit version.

If you have an existing HASP key which is valid for version 1.x, the most recent 1.x release is dBSea 1.3.15 

If you experience issues with the most recent full version due to the introduction of server licenses, the most recent release prior to the introduction of server licenses is dBSea 2.3.6.
