I need help. I just opened my wallet today for minting and noticed that it's not syncing anymore. Then I saw the mandatory update to 1.7 wallet (i'm on 1.5 now) in OP and need your help. I'm a tech newb and I'd appreciate if anyone can take me step by step process on how to update wallet. Safest method will be appreciated. Thanks in advance!
Hey vtbean, I'll do the best I can!
First thing you will want to do is backup your wallet.dat file. Back it up in multiple locations (you should keep it backed up at multiple locations all the time- you only need to reback it up whenever you add a new address to the wallet). You can back it up from within your wallet using file => backup wallet.
Now you will want to find your "roaming" folder. First, make sure you can see hidden files and folders. Then, to find the "roaming" folder, if you are using windows, search for %appdata% in the search bar on the start tab (I'm not sure how to find it on a mac/linux, but I imagine it is an analogous process). Once you have located your "roaming" folder, locate the "MintCoin" folder within it. Delete everything from this folder
except for your wallet.dat file (it would be fine if you did delete it since you backed up the wallet.dat file elsewhere, but there is no need to delete it
so don't take the risk).
Now that everything is deleted, except for your wallet.dat file, download and run the new v1.7 wallet. You will need to download the entire blockchain again.
Edit: well that took too long for me to type, looks like others already covered it
