Hi

I'm running Windows 7 Beta 64-bit.
I've downloaded AVR Studio 4.16 and installed it. I have no luck getting my AVR Dragon to work though. At first it says "An service installation section in this INF is invalid".

I then forced the device manager to use the windrvr6.sys file located in the usb64 folder of AVR Studio. The device is then installed properly and both the green and red LEDs on the Dragon are lit.

Unfortunately, AVR studio simply says "Connection Failed" whenever I try to use the Dragon. Do you need to have a target connected before you can get a connection to the Dragon? I also tried doing a firmware upgrade from the Tools menu, but it also fails to communicate with the programer.

Is there something I can do? Will I have better luck with a AVRISP mkII?

Update:

When installing the windrvr6.sys driver, the name of the device changed to "Windriver". AVR Studio still could not connect to the programmer.
I then uninstalled the Windriver device and driver, and it was re-detected as an "AVR Dragon" and the driver installed fine. I read that someone had luck after copying the windrvr6.sys file to System32\Drivers, which appears to fix the INF error above.

Still no luck in getting AVR Studio to work with the programmer though. See the attached screenshot of the device manager.

I did similar experimentation with Win7B/64 and never got AVRStudio to detect the Dragon or JTAGICE mkII. I think the .inf problem has to do with the directory destination for windrvr6.sys, and that the manual placement is a valid workaround. I also tried the latest download from Jungo. It appears the driver renames itself to whatever device is connected.

Did you ever manage to get it working with AVR Studio though?

Update: I just installed Windows 7 32-bit on another partition and it works flawlessy with the AVR Dragon, which leads me to think that the issue is not specifically with Windows 7 but with 64-bit. Which leads me to the question:

Has anyone ever managed to get the AVR Dragon working with AVR Studio on Vista 64-bit?

I'm not sure about the AVR Dragon, but I was able to run the AVRISP mkII in Vista 64 no problem. I did have the same issue as you with the AVRISP mkII in Windows 7 64-bit, but believe there is a workaround.

You can install AVR Studio and whatever programmer you are using in the "Virtual XP" mode for Windows 7. It's basically just running a Windows XP virtual machine. The files you need to run are free and available on Microsoft's website. I have been able to connect and program this way without any problems.

Hope this helps.

I just had the "An service installation section in this INF is invalid" error on 32 bit Windows 7. I copied the windrv6.sys file to /windows/system32/drivers and it let me install the driver, but AVR studio won't recognise it.

Has anyone managed to get it to work in Windows 7, or heard anything from Atmel about Win 7 support?

I asked support about this issue, they said there are plans to support this OS but no schedule yet.

But Windows 7 isn't released until October 22nd. You can hardly expect Atmel to support an OS that doesn't officially exist yet can you?
