You'll have to update the STK500 firmware which wouldn't work for me initially. After
fiddling around for half an hour I unchecked the STK500 plugin then rechecked it. After
that it installed ok using the manual update procedure detailed in the STK500 help file
and works fine for me:

STK500 Manual Firmware Upgrade

The current version of AVR Studio will automatically detect any old STK500 firmware
version and request the user to upgrade the firmware. If for some reason the upgrade fails
(the serial cable is detached during upgrade, the power goes out, ...) the next time the
AVR Studio tries to connect to the STK500, the board will not be detected and the
automatic upgrade procedure will not start. 

Following is a procedure on how to manually upgrade a STK500 board. This procedure should
work in all cases:

Power off the STK500 
Push the 'PROGRAM' button (located near the AT45D021 dataflash) while powering up the
STK500 
Start AVR Studio and make sure there is a serial connection between the PC and the STK500
DSUB9 marked 'RS232 CTRL' 
Start the program 'Avr Prog' located in the AVR Studio 'Tools' menu 
Locate the firmware upgrade hex-file 'stk500.ebn' by pushing the 'Browse'-button in the
'Avr Prog Hex File'-window. The path for the 'stk500.ebn' for a normal AVR Studio
installation is "C:\Program Files\Atmel\AVR Tools\STK500". 
Push the 'Program'-button in the 'Avr Prog Flash'-window. A progress bar will now appear
while showing additional information messages. Wait until the verify operation is
finished. 
Close the 'Avr Prog' program 
Power off and on the STK500 PCB. The STK500 is now ready to be used with the new firmware.
