If anyone has tried these drivers with Windows Server 2008 R2, please let me know. Thanks.
You really don't need the following information, but I leave it here for historical purposes.
Windows 7 again impressed me when I needed to load up my FA-101. I use the FA-101 as the only audio interface on my studio PC.
Doing a quick search you will find that there are no Windows 7 64 bit drivers for this device and if you try to run the Vista installer (FA_101_Vista_x64_Ver.1.0.4) you will get an error that it will not run for this version of Windows.
All you have to do is run Windows 7's (very cool) "Troubleshoot compatibility" wizard.
I have found the FA-101 to be much less susceptible to problems under Windows 7 than under Vista. Although the FA-101 driver did not contribute to my former 64 bit Vista's instability, the driver itself would frequently seem to get stuck. I was very used to powering off the FA-101 to un-stick it. So far, that has not been necessary with Windows 7. It continues to shine!
