Dear Technical Support representatives,

I know the 64-bit client is not officially supported, but may be you could tell me why it doesn't let me set any compatibility settings, such as 'Disable desktop composition', in the file properties? The whole 'Settings' section is grayed out: http://imageshack.us/photo/my-images/716/wow64compat.jpg/ I can disable desktop composition for the 32-bit client just fine. I'm using Windows 7 Home Premium 64-bit, version 6.1.7601 fully up to date, including all drivers.

Thanks!
