The wallet.aro file should be located in C:\Users\YOUR-USER\AppData\Roaming\Arionum
Try to copy that file and put it in the cli wallet's folder.
I made the exchange of the file and I can see my balance in wallet.aro's wallet.
but when I try to restore the wallet windows on another computer (Restore> Select file> ok> I type my password) it still gives the error "could not import the wallet. the keys seem invalid"
I am not typing the wrong password because when I type wrong I purposely receive the message on the screen "invalid wallet password"
