For IAR Embedded Workbench for AVR version 5.40 to 6.10, run the batch file
install.bat. The batch file is located in the directory
avr\driversin the product installation.

- If you are using 64-bit Windows XP:
The JTAGICE mkII driver can, from version 5.40, be used on 64-bit versions of Windows Vista and Windows 7 but not 64-bit XP. If you install AVR Studio Version 4.18, with Service packs 1 and 2, this will update the USB drivers, and the firmware in the JTAGICE mkII. IAR Embedded Workbench for AVR 5.40 will then work on a Windows XP 64-bit system.
