Question: Does this work with windows 7 64 bit? I see a lot of customer reviews with issues on this.
Document: Despite other reviews I purchased this device and found that it worked flawlessly with Windows 7 64 bit version. Easy setup. Sound quality and range are great.
However, Windows 8 has pretty good built-in support for Bluetooth, so you won't feel the lack of manufacturer drivers as badly.I misunderstood other reviews and thought it was just the APT-X that does not work on 64-bit. No, many standard Bluetooth devices will not work with this dongle if your computer is 64-bit.
Other reviews are correct; this device is not worth buying if your computer is 64-bit and running Windows 7, which most computers sold in the last five years are. Until I tried this device for myself, I didn't realize just how far this dongle's limitations on 64-bit went.While this dongle works fine with Windows 7's built-in drivers, those drivers are anemic and do not support many common Bluetooth devices.
Pros: Looks cool, blue light is not too bright. 2) I just plugged it in and worked, i heard that the driver CD can be tricky. The range seem to be accurate, impressive.Cons: The metal part is visible, could bother some people. 2) The biggest problem for me is that the quality sucks, very statistic. Now i looked in the reviews and found a guy that said he had the same problem and apparently its not compatible with windows 7 64 bit.
I received the Azio-BTD V400 knowing that some people had problems using it for their Windows 7 64 bit laptops, but I figured that since the description says it is compatible with Windows 7, and I have some tech knowledge, that I would be able to get it to work. Unfortunately, it is INcompatible with Windows 7 64 bit.
Saw an awful lot of fuss about this not working on Win-7 64-bit.Dunno what THAT was all about ... it works perfectly. It DOES take a good long time to get all of the various drivers loaded, but I have three other older (non-AptX) BT dongles, and they AL take forever to fully install.Almost invisible; GREAT AptX sound.Do it!
I've spent about two months trying to get this thing to work and I've stopped getting responses from Azio and CSR about it.This does not work on Win7 64 bit systems. There's a registration failure during installation and several BT profiles are not available, so I cannot use my Bluetooth stereo headphones with this device.The error is easily reproducible so I don't see what the delay is in getting out a version which supports current 64bit operating systems.
And the drivers for this dongle (and, indeed, all dongles that use Cambridge Silicon Radio parts inside them) do not work right on 64-bit Windows 7.
A2DP (stereo audio) will not work on either of my Windows 7 64-bit computers. It still works great on Windows 8 32-bit.Lowered my rating from 5 stars to 3 stars, averaging 5 stars for Windows 8 32-bit and 1 star for Windows 7 64-bit.Jim
Ordered two of these to install on two separate Windows 7 computers, both 32 & 64 bit. These devices work as long as you don't installed the supplied drivers - but then they only work as basic BT adapters. However as basic BT adapters you don't get all the features such as Apt-x, BT 4 LE, etc...As soon as you install the supplied CSR Harmony drivers things start to break on both Windows 7 32-bit and 64-bit.
