Hi mates, I installed yesterday 4games launcher, then installed Ragnarok online, Lineage 2 and RF Online. After that i close the app and shutdown my laptop. Later pick it again and run the launcher. but it doesnt start. It tries to run, but instantly close all related process. Launcher appears in my task bar and system tray while loading, even spiral animation at middle of screen, but dont reach to open the window until it close. I put a ticket, but meanwhile 4games awnser me i thinked may someone see this problem before. FYI i tried to reinstall launcher many times, reinstall windows 10, run sfc /scannow and DISM commands in CMD, run ccleaner, tried install and remove my web browser (in other threads i read something about it may affects so i tried), see the windows registry searching i don't know what, even download an app from 4games named check4game and tried to see if something isn't working, but all is correct at my sight, no errors and hosts file is empty. My windows is 10 pro 64 bit version. And my laptop specs are: Ryzen 5 3550H With Radeon Vega 8 AMD RX560X as dedicated graphics 8GB RAM 512GB Kingston SSD. Hope someone reconnice this and can help me find how to make it works. Thanks!
