Make sure Roblox is not open in your tray.
This is a known issue which can potentially be solved (?) by manually launching Roblox via command line. This would require implementing an account manager into Multiple Roblox Instances, which is outside the scope of this application.
That is no problem, as that function does not interfere with Multiple Roblox Instances core function. See "Is Multiple Roblox Instances compatible with Roblox launchers?" below.
Also no problem. If your launcher has a fix for Error 773, you may see some message about Multiple Roblox Instances failing to apply a fix. See "Is Multiple Roblox Instances compatible with Roblox launchers?" below.
Yes, but there has been no recorded instance of people getting banned for using Multiple Roblox Instances.
Yes, but unrelated functions in Multiple Roblox Instances may break (i.e. UI will not show running accounts).
No. Only one Roblox account can be opened per instance (i.e. try opening Roblox on your computer, then opening Roblox on your phone).
As many as your computer can handle.
No. Only one Roblox account can be opened at a time.
No. Multiple Roblox Instances is for Windows only.
new Mutex(true, "ROBLOX_singletonEvent");To fix Error 773 related to teleports, Voidstrap makes RobloxCookies.dat, found in LocalStorage of the Roblox folder, write-only. See this.
Similar behaviour can be achieved by locking RobloxCookies.dat:
new FileStream(System.IO.Path.Combine(RobloxPath, "LocalStorage", "RobloxCookies.dat"), FileMode.Open, FileAccess.Read, FileShare.None);
This can cause side effects in Multiple Roblox Instances, making the application potentially incompatible with Roblox launchers.
