I copied the file into electrum wallet directory ( C:\Users\XXXX\AppData\Roaming\Electrum\wallets ) but, the program doesn't starts
Do you have a folder called "certs" in the folder along with files "config", "daemon", "blockchain_headers" and "recent_servers"?
If these files are missing, copy the default_wallet.file to a different lace and try to create a new wallet. Once the new wallet is made, all of the other files and folders will be set up correctly and ou can recopy the default_wallet.file.
(But first check that you have definitely decrypted the seed correcty for it to be loaded into the electrum wallet).
