Applications out of date and can't be enabled

[All Cars Online]

Morning,

I'm in the process of building my site and decided to purchase IP.Gallery and IP.Nexus. Downloaded the ful package from my client area, upload it in the normal way and then installed it.
However, in the Applications page, it shows that both packages are there but it says they are out of date (even though the version numbers all match that of the board). It's telling me the application is locked and can't be enabled until it's updated.

I can access some fo the features/options but I'm unable to edit the permissions.

Is this a known bug or am I missing something?

Just a theory, based on the possibility that the site was running < 4.13.2 prior to the addition - run http://yoursite.com/admin/upgrade

Thank you
It wasn't that straight forward as I didn't always see the upgrader and when I did it's taken 5 attempts to complete it

Anyway, it's all sorted now
