A second PC with XP is of course an option. On the other hand,
there are other solutions.

If you are using Windows 7 Professional/Enterprise/Ultimate Version,
you can download XP Mode for free and it should work as well.

Home Premium version can be upgraded for a fee.

If not, you can try VirtualBox.

Above instructions are not always applicable, at least, not on my Windows 7 64 bit HP EliteBook, because for some usb 
port virtualization does not work.

The only thing I had to do is to get libusb-win32 driver 1.2.6.0, change set_configuration.c in order to replace bulk 
with interrupt transfer in the driver, then compile and install it, at voilà, now I can use both eclipse ide and CF 
Flasher 3.1.
It would be wonderful if somebody could sign the driver with a valid certificate, so it is not necessary to enable 
TESTSIGNING in order to use the driver.
