Managed to install Ragnarok Online on POL. However when I try to run the Setup.exe which should open the ro settings when you first run the client, I got missing dlls error. So what I did is copy those missing DLLs to the folder where I install Ragnarok.
Now I try to run again the Setup.exe and I got this
wine: Call from 0x7bc40740 to unimplemented function ntdll.dll.RtlCreateTagHeap, aborting
err:module:attach_process_dlls "KERNELBASE.dll" failed to initialize, aborting
err:module:LdrInitializeThunk Main exe initialization for L"C:\\\\Program Files\\\\RagnarokPH\\\\Setup.exe" failed, status 80000100
