New versions of MultiBit Classic are released containing bug fixes and new features every so often. We recommend you keep your version of MultiBit Classic up-to-date.
This guide tells you how upgrade to a newer version. It is assumed that you have reviewed the Getting Started guide and know where all your wallet files are.
If you have a standard installation (i.e. you followed our installation notes) upgrading MultiBit Classic should be a seamless process. Your wallet and configuration files will not be in the same directory as the MultiBit Classic application.
Note: You can create new wallets in any directory however we recommend you store your wallets and configuration files separate from the installation directory.
You can always see the file location of your current wallet in the main title bar of your MultiBit Classic window. For instance, it might say: "MultiBit Classic - My wallet - /Users/jim/Library/Application Support/MultiBit/multibit.wallet". The file name at the end is where your wallet is stored.
If you have stored your wallets in the MultiBit Classic installation directory (this is not recommended) and want to move the wallets out of this directory then please review the Moving A Wallet article.
Follow the standard installation instructions for your computer.
Once you are happy with the new version of MultiBit Classic there is a uninstaller shortcut provided so that you can uninstall the older version of MultiBit Classic.
This is not required on Mac OS X since MultiBit Classic.app is simply overwritten.
That's all there is to it. MultiBit Classic will alert you if there is a problem and the main help contents provide answers to many common questions.
