ZIBO Updater is a packaged as a portable executable. This means that ZIBO Updater is not 'installed', and is ready to use straight after it is downloaded (you can get it here).
Saying that, best practice is to make sure that you do not do the following:
- Run ZIBO Updater from your Downloads folder - this can cause permissions issues.
- Run ZIBO Updater directly from the C:\ Drive - et al.
- Run ZIBO Updater directly from the <x-plane 11>\Aircraft\B737-800X directory.
In summary, you can place ZIBO Updater wherever you'd like. The application allows you to create a desktop shortcut from the settings menu, in the utilities page.
