[LAUNCHER] Failed to download XML

Thanks to Tualens, we've found a solution (not sure if its work for everyone)

Certain version of windows force the use of a wrong TLS (a service that work in pair with .NET).

Solution is to add new key in your regedit that force your windows to use another version of TLS.

Two method possible to do that :

1. Hard way, opening regedit and adding each new key manualy

adding the following registry keys:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft.NETFramework\v2.0.50727]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v2.0.50727]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
"SchUseStrongCrypto"=dword:00000001

2. Easy way, thanks to Nellkee, we have a .reg file that automaticaly add these keys to your regedit.

https://we.tl/t-kj12OCk2X2 <- Here is the link to the .reg file.

Download it, launch it, it will ad needed key, then launch the RoRLauncher and it will be fine, normaly.

Just a heads up, there might be an error in some cases in the reg file, a "\" could be missing between the "Microsoft" and ".NETFramework"

For example:
[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft.NETFramework\v2.0.50727]

should be

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\.NETFramework\v2.0.50727]
