Sorry to revive a dead topic, but what if you click OK to the error but it just pops up again? I also tried opening my setup.exe(the options one) and i copy pasted one from one installer to the RO folder im using now. When I launch my server's patcher and press start, the Setup window (for RO options) show up, but when I press "OK", it pops up again instead of my client's game. Any insights or suggestions or ideas why?
