Download version

I have been alerted to download a program update. Which version should I use - I get confused by all the alternatives. I am a humble, simple-need individual who uses ownCloud for safekeeping photos.

Hi Susi,
is this regarding your Desktop client or do you want to update your ownCloud server installation?
For the server installation there is a manual on how to upgrade:

I think I’m in even deeper trouble, I cannot even log in, so I’ll have to contact support. I’m pretty sure I’m NOT a Desktop client. My photos are stored on the ownCloud server. Thanks anyway for your feedback!
