gvSIG-Desktop 1.12. User manual

From the menu Tools / Complement Manager select 'Installation from file', choose the .gvspkg or .gvspks file you want and click 'Next'.

Add-ons Manager: installer selection

With this option you can install add-ons that have been previously packed in .gvspkg or .gvspks files.

After selecting and accepting the file in question, appropriate add-ons are added to the list of plugins by default, either in the official add-ons tab (those that have been through the gvSIG process of formalizing) or in the unofficial tab.
