I have a bitcoin application from 2009. I would like to try to get it running again to see what's in it?  Any help?  I have it saved on windows 7.
It's not the application nor its bitcoin install folder that you need, it's the "bitcoin" data directory (folder) that it created in 2009.
That's where the most important file "wallet.dat" would be.

Check your Win7 PC's %appdata%/roaming/bitcoin folder to check.
If you found a "wallet.dat" file, make a few copies of it immediately for backup purposes.

Then decide if you want to immediately sync it on an online Bitcoin Core client (not recommended for that old wallet) or just export its private keys that can be spent "cold-storage style".
