beta version 2.5.0.8 has been found to work with 32-bit installs of Windows 7. IP driver is in the process of being rewritten to support future OS. IP driver is not supported under 64-bit OS currently.
64-bit drivers are a little harder to make because of new policies at Microsoft from my understanding. It is more than just code at this point. I am not aware of the timeline, but I can tell you we are looking into it.
as a side note to this subject version 2.5.2.3 of IP driver fixes naming convention as it has been changed in Windows Vista and 7. This is fairly important when it comes to OEM versions since earlier versions would show all I/O as the same name in Windows. 2.5.2.3 resolves this new method in which windows identifies device names.
Any word on the ability to record via ASIO @ 44.1 in the final build, or will the ASIO4ALL device be required? Just tried it with 2.5.2.3 with no luck.
A majority of our third parties & remote submission systems are fixed at 44.1 so it just simplfies life greatly.
