So I've recently dug up my old Lego Mindstorms RIS 2.0 (RCX) and have spent the past few days trying to install it into my Windows 7 laptop. It worked fine, except it could not find the correct drivers for the IR tower. Installing it on a Windows XP Virtual machine has given the same result.

Any suggestions/patches?

    Do you also have a PC with a Linux install? That is how I'm using my old RCX 2.0. If you do I'll put up an answer with the Linux info. – pcantin Aug 26 '12 at 12:55
  • USB or traditional serial? I assume the former, but both were common in the rcx days. – user3971 Jul 20 '16 at 12:52

I have the RCX IR tower setup and working on my Windows 7 laptop. I downloaded the drivers from the ROBOTC.net site here (labeled 'RCX Device driver')

Direct file download link

Note: I am running Windows 7 32-bit, according to the ROBOTC site, this driver is 32.bit only and

No known 64-bit driver is available for the RCX.


I searched for this problem as well and want to share my solution with you.

I am on Windows 10 64 bit and had no driver.

So I did these easy steps:

  1. Go to Device Manager and select the USB TOwer
  2. Go to Driver/ Update Driver
  3. Select: Search on this Computer -> Select out of a list on this Computer
  4. Pick the LEGO MINDSTORMS NXT Firmware Update Mode -> Install

Hope I could help someone with this.
