Entities – How to install the Feature Browser module?

I'm trying to install the Feature Browser module, but I get this error:

Fault

It basically says that the entity type "entity_browser" does not exist, and depending on the error, I tried to install the type of entity missing , using drush:

Error while running drush entup

Once I ran drusn entup I was asked to install the missing entity, but drush ended up returning the same error that I get in the browser.

Could I miss something?
