Turbo Quattro

Thanks, but it didn't helped. Maybe you have some more info? It's not clear what encryption method was used, neither what was IV. E8C040FA7AE8F580FC F9EDAB3EC4CDC003EF9775 is 20 bytes length - not sure where to use that one.

Thanks, thats helpful

Is it safe to update from AU57x from 2519 to 3663? If I just want newer version?

Hello, I was wondering how to do it on my own.
Password found in xml - is base64 encoded 16 bits hex.
That longer "zip password" is base64 encoded 32 bit hex. That could be AES256 encryption key, but even if I do use decrypt with IV all 00, I get some rubish in output.
Anyone can give some guidance?
