Plugins downloaded from the CLC bio website have the  file extension .cpa .

When working on a Windows system and using Internet Explorer, you may find that when you download plugin files they have the file extension .zip .

If this happens, the simplest solution is to use a different browser software, for example, Firefox or Chrome, to download the plugins.

For any Workbench running on a machine connected to the internet, we generally recommend using the Plugin manager within the Workbench for downloading and installing plugins.
