World of Warcraft Launcher

Greetings. I am looking for someone who can fix a World of Warcraft Launcher. It is made in C++, but for some reasons, it is not working anymore.
The launcher is connected through FTP, and we need to put some folders and files in the Webhosting, in order to auto download and auto update the patches.

Problems:
1. It is not downloading or updating the WoW Client
2. It is asking for Update the program, but when you click on "Update", it doesnt open the Launcher anymore (so this should be deleted)
3. The Launcher should be a installable .exe file , so the player have to install the launcher.

How we'll work:
1. Im not paying in front (too many scams)
2. Im not assigning the project till the Launcher is not 100% working (too many scams)
3. I can send the Source Code so you can work on your side, or you can try to fix it via Anydesk or Team Viewer
4. IF YOU DO NOT READ THE ENTIRE TEXT, AND JUST APPLYING WITH A AUTOMATIC MESSAGE, YOU WILL BE REJECTED INSTANTLY. MY AND YOUR TIME IS IMPORTANT. DUE TO MANY SCAMS, IF YOU'RE INDIAN / IRANIAN GUY, IM AWARE TO WORK WITH YOU, DUE TO MANY SCAMS

Please read the entire text, and if you agree with them, message me. Thank you for your time
