I'm sure I'm not the only one who has had this problem and after a week of researching, I'm finally breaking down and asking. I think I mentioned in another post that I'm running 64-bit Windows XP and cannot seem to get giveio.sys to load using avrdude-gui. The error I get when I try to install is "This driver has been blocked from loading." Then when I try to upload, I get "can't open device "com1": Access is denied."
I've googled for the errors and searched on avrfreaks and can't seem to find anything that applies. If I can't get this figured out, I think I'm going to get one of the more expensive programmers. I'm currently using the AVR STK Serial Port Dongle Programmer (http://www.sparkfun.com/commerce/product_info.php?products_id=14) and am considering purchasing the AVR In Circuit Emulator with USB Interface (http://www.sparkfun.com/commerce/product_info.php?products_id=12).
Any assistance is appreciated. Thanks!

Hey,
When using ic-prog to upload my code I had to install something first to "unlock" the serial port, Maybe you could look at the ic-prog website and see if you need to do something similar
-
long shot but is your programmer connected to port 1 or is it a different port. You can check from the device manager.
-
It's connected to com1, my serial port. I don't have a parallel port.
-
perhaps two different programs are trying to access your programmer at once? I get this error when ever I am using a serial port for a data logging program and then try to program with it without closing the program.
-
I've never used anything else on my serial port. I've read somewhere that perhaps the mouse drivers might try to use it, but I don't know where in my system to check for that.
-
to check what's using your com ports go to Start->Settings->Control Panel->System.
-
As far as I can tell, nothing else is using my serial port (including me :-\).
