To return for a bit or not to return.

It's a matter of compatibility of "Setup.exe" most likely, if you're using the one with a ghostring icon it usually don't work with heRO's current client. Installing RO in "Program Files" usually blocks Setup's full functionality too and I've noticed you have it in there.

I recommend you to try the older version of "Setup.exe" and make it run in compatibility mode for Windows XP, or try Opensetup both in REG (registry) and LUA modes to see if either options work. If not, you can use "ROExt" (for windowed mode at least) with or without the tool pointed by The Legendary Joe.
