Can't get WP8.1 preview

[jjacks90]

I installed the "Preview for Developers" app on my Nokia 521. It is unlocked with a dev account. I go to "Settings->phone update," and I see that there is an update for my phone. But it says I need 10.00 MB of space to install it so my phone won't install the update. I really have 2 GB of free space so the message doesn't make sense. I can't get past this. Has anyone seen this? Do you know how to get past it?

Could it be that you need 10 MB more to do the install? I'm not sure because I haven't encountered that problem. But my suggestion would be to either remove pictures or music (move to cloud or PC temporarily), or if you don't have those on the phone, uninstall a bigger app (like a large game), or delete downloaded maps, to make room for the install, and then reinstall after you're done.
