Hello, my problem is very vagueness but I just can’t install FiveM.
The first problem began after the last update of FiveM, I had a problem with caches.xml that I deleted a lot of time, after that I went to your forum and in a topic, someone advised to unistall and reinstall FiveM, that is what I did. But my main and second problem appeared, when I try to install FiveM, I execute the launcher “FiveM.exe” and there is a first message :

but sometimes when I execute the launcher to try to install FiveM, there is an other message :

but when I select “Oui” (“yes” because i’m french) the downloading is infinite :
(I know that because I let my pc turn like this during 3 days and nothing change). That’s why my FiveM’s folder is empty and I can not install FiveM…

If somebody can help me pls, because I have this problem since 2 months.

I don’t have a VPN, I tried to unistall my antivirus but it change nothing, and when I go on the website of the first error message, there is this message :

So, yes I think that probably I have some other issue on my system but where and how correct it ?
