Getting the IR Tower working with RCX and RobotC [duplicate]

Lego Mindstorms RCX RIS 2.0 IR tower Windows 7 / Windows XP driver

Trying to get RobotC to work with my old RCX 2.0. I'm running windows 7 64 bit. I've connected the IR tower via a Serial to USB cable. I get the error from RobotC when I go to send the firmware "RCX Controler Failed to Respond"

I'm assuming this is because the drivers are for 64 bit only. Has anyone had success running a WindowsXP virtual machine and trying the drivers? Or any luck getting RobotC and the IR tower running on a Win7 64 bit machine.

Answer 1

Please see this question: Lego Mindstorms RCX RIS 2.0 IR tower Windows 7 / Windows XP driver Basically there are no 64bit drivers available and the OP on the question I linked to says he had no luck with an XP VM either.
