Do you recognize this wallet from 2014

Is there anyone that can recognize this wallet? It is from  https://ibb.co/yNLTr9h

The language is danish because I´m from Denmark, but I guess that there must be someone that can recognize it from its design. I hope.. It is literally the only clue I have to my old wallet from 2014.

I cross my fingers that someone can help.

Bitcoin Core, previously known as bitcoin-qt. See the News link above this page for a download link.

Note: your wallet is most likely named wallet.dat. Make a backup on a USB-stick before doing anything, and then make another backup on another stick just in case. Even a third backup doesn't hurt, better safe than sorry.

Is that a brand-new screenshot of the software synchronizing or did you have it somewhere on your computer from before? What version of the wallet do you have installed? It's a good thing that it's synchronizing, which means that it's most probably not corrupted (at least for now). If you are planning to keep using Bitcoin Core, you are going to have to download the entire blockchain and wait for the wallet to fully sync. You need to download the latest version as well like LoyceV pointed out. If you don't want a full-node, you can dump your private keys and import them into an SPV client like Electrum. Electrum doesn't require that you keep a copy of the whole blockchain on your hard drive.
