There are some issues with running Atmel Studio under the Windows 8 preview. One is that the backend part of the program does not start, another is problems with the certificate for the Jungo usb driver.
Workarounds for now:
Locate the folder avrdbg in the installation, defaults to
C:\Program Files (x86)\Atmel\Atmel Studio 6.0\avrdbg on 64 bit system.
Copy all the dll-files into the codeCache-folder. This should get the backend running.
To fix the issue with the drivers, the Atmel certificate must be installed.
Locate the file
Access Properties->Digital Signatures.
Select Atmel Norway and Details
Select View Certificate
Select Install Certificate
Select Local Machine and default for the rest
This should install the certificate.
Then the drivers must be updated.
Open Device Manager, locate the Atmel Tools drivers under Other (the ones with a yellow mark)
RightClick->Update Driver->Search Automatically.
And you are set.
Only tested on Windows 8 64 bit.
We will post an update to AtmelStudio fixing this, but the above steps should get you going for now.
