Luckily, I figured out how to solve it. To whom having same problem, try this VMsolution:
1. Run Command (Run as administrator).
2. If your GB_Serve is in C:\, copy sequentially these below command and press Enter for each (if not, change your respective address):"C:\Gb_Serv\Server\BuddyCenter\BuddyCenter2.exe -install"then close the Command window, run the start-sever.bat as the tutorial.
"C:\Gb_Serv\Server\BuddyServ\BuddyServ2.exe -install"
"C:\Gb_Serv\Server\Center\GunBoundCenter2.exe -install"
"C:\Gb_Serv\Server\Gunbound8360\GunBoundServ2.exe -install"
"C:\Gb_Serv\Server\Gunbound8361\GunBoundServ2.exe -install"
"pause"
Hey Bro, i done what you say to do, but after this i try again to use the instal.services but continues that error, just do this in cmd manually is sufficient to instal?
