You can extend the IDE with plug-in modules using the Update Center. Choose Tools > Update Center to check for new or updated modules.

You can also update modules in the IDE without having to connect to an Update Center server. Manually download the NBM file of the module you want to update. Then choose Tools > Update Center and select the Install Manually Downloaded Modules radio button in the first page of the wizard.

To stop the IDE from automatically trying to connect to the Update Center:

  1. Choose Tools > Options.
  2. Expand the IDE Configuration node. Then expand the System node.
  3. Select the Update Center node and set the Check Period property to Never.
