giveio blocked from loading

[javafiend]

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 and am considering purchasing the AVR In Circuit Emulator with USB Interface.

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.

[Darkbluestar]

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  ).
