FWIW, I tried to duplicate this after a fresh install [1] of 2.30.01 under Windows XP Pro SP3 and the result was that I only got one entry in my Startup folder.
[1] I didn't run FindAndRunRobotInstall.exe to install -- I just unzip FindAndRunRobotSetup.zip and run FindAndRunRobot.exe from within the resulting folder.
