Hi.
Since I needed to patch music of UO, and UOGateway is not able to do it, I've developped a software doing this.
After instalation, the user need to enter at first time the UO client path.
At the first time, this launcher also copy new musics in UO Client if needed, and uncrypt the client using an external software (UORice).
Each time the software is launched, it logs on a FTP server, check if a new update is needed, eventualy download the update package (same RAR than UOGateway, so, it's compatible). It also show an info message that the admin can change on the ftp server.
The launcher is launced with a music.
