AHK: open and resize the same program twice

[Dr. Boom]

What's up everyone


so I'm having this little plan to use the program autohotkey (AHK) to open the same game (same path, same title) twice, then wait for its launcher to load the actual game and then move + resize both instances of the game at once so they appear next to each other like this:

So the only way I'm getting this done is opening the game a second time AFTER the first one is already resized but that's pretty meh (the sleep time waits for the launcher to be done loading the actual game).

Run, "C:\Users\Chris\AppData\Local\RuneLite\RuneLite.exe"
Sleep, 10000
WinMove, RuneLite,, 0, 0, 960, 1024
Run, "C:\Users\Chris\AppData\Local\RuneLite\RuneLite.exe"
Sleep, 10000
WinMove, RuneLite,, 960, 0, 960, 1024
return

Also tried to filter out if one of the instances is minimized or notActive and similar stuff, but that didn't do anything and I don't know what to do next, so maybe someone here has an idea

Edit: So as it seems the problem is solved and for those who care, the way it's done:

Loop, 2
{
    Run, "C:\Users\Chris\AppData\Local\RuneLite\RuneLite.exe",,, %A_Index%PID
    WinWaitActive,% "ahk_pid " %A_Index%PID
    Sleep, 5000
}
WinMove, ahk_pid %1PID%,, 0, 0, 960, 1024
Sleep, 3000
WinMove, ahk_pid %2PID%,, 960, 0, 960, 1024
return
