Hi,

I've finally managed to get my PT 6.4/original Mbox to run using Windows 7, sort of, through Windows Virtual PC, which is a virtual machine that runs a program called Windows XP Mode. Here’s what I did:

1. Installed Windows Virtual PC from here: http://windows.microsoft.com/en-US/windows7/install-and-use-windows-xp-mod e-in-windows-7
2. Opened Windows XP Mode.
3. Copied the Protools and Digidesign folders onto the Windows XP Mode platform.

Initially, when I ran “driver setup” I had a .dll file problem message come up. Someone suggested I download a file called “asio4all” http://www.asio4all.com/. I did this then ran the driver setup again and it worked. However, this might have been a coincidence, because I then had problems with the virtual machine, i.e. with the “Enabling Integration Features”, and this locked me out. I resolved this by changing the settings from “Automatically close…” to “Prompt for action”, then from “Hibernate” to “Turn off” (right click Windows XP Mode in Explorer, Settings, highlight “XClose”, “Prompt for action”). This seemed to free up the problem. I then changed the settings back to automatically hibernate, as it starts up much more quickly when in hibernation. I later uninstalled the asio4all file and rebooted my pc to test whether Protools would still run and it does, so I don’t know what to think.

The only problem I now have to resolve is when I either play or record a music file in Protools, after a few seconds it freezes and a message comes up that says:

“Audio processing is conflicting with other CPU tasks. If this occurs often, reducing the “H/W Buffer Size” in the Playback Engine Dialog may help prevent the problem (-9129)”

However, when I reduce the H/W Buffer Size and run a file, it too freezes and another message comes up telling me I need to increase the buffer size!

Also, if I connect speakers to the line output from the Mbox to listen to an audio file, there’s a lot of noise. It sounds like the speakers are picking up any work the pc is doing, such as loud crackling when I connect/disconnect the Mbox, noise when I drag the mouse curser across the music file, and every other computer noise.

Does this sound like a CPU problem or something else?

I’m running Windows 7 Professional 64bit on a Toshiba Satellite Pro L770 with 4GB RAM and 2.3GHz CPU.

Thanks in advance.
