Windows desktop client doesn't check for updates

I installed Owncloud client 2.3.3 on 2 PC, both with Windows 7 64 bit.
One has correctly detected a new release 2.3.4 and installed it, the second is still stuck
on the old version and there's no way to manually tell him to check. Here is a screenshot.
How can I force the update check ?

Thanks and bye,

Your screenshot does not load for me here? :frowning:

Neither for me :slight_smile:

It should be visible now
