Body: <p>I have looked for similar question but found null. So here I am asking.</p>
  
  <p>I have Win7, a RobotC fo RCX and Mindstorms for RCX (both are old version, but available free). I borrowed an old LEGO kit (9794 Team Challenge) which lacked some parts. It has RCX 1.0 as controller. I borrowed a USB IR Tower from my friend.</p>
  
  <p>After a well installation, I tried RobotC and was asked to download firmware to RCX brick.
  But RobotC cannot communicate with it because it cannot find the port which I plugged the IR tower to. Inside the preference, there are two available USB port recognized.</p>
  
  <p>I swithced between them but RobotC still cannot find the tower. I have been googling this around for almost a month now.</p>
  
  <p>Thanks for any enlightement.</p>

  If you are you using ROBOTC 2 for RCX you need to install the [**separate driver**](http://www.robotc.net/files/rcxdriver.zip) for windows 32bit. This driver is not included in the ROBOTC install (at least not with version 2.03).
  
  It might also be a good thing to start with a fresh install of [ROBOTC 2.03](http://www.robotc.net/files/ROBOTCforRCX_203.exe).
