Electrum setup problem I was trying to install electrum, and for some reason, I wanted to see what multisig wallet was, and now I'm stuck on the master public keys window, I can't cancel and select standard wallet. Every time I open the installer it asks me to input the master public keys.
Just had this problem today. You need to close Electrum, delete the Electrum folder, and start Electrum again. This will "reset" the installation.

The Electrum folder is ~/.electrum on Linux and Mac. On Windows it should be Users\&lt;YourUserName&gt;\AppData\Roaming\Electrum\wallets (it's shown without slashes on the official Electrum website but this should probably be where it is). You might need to show hidden files in order to see it on Windows.

Note that this folder contains your wallets so if you have existing ones, you'll want to back them up first.
