Quickcam Messenger working on Windows Vista / Windows 7 x86
Windows 7 RTM x86
The following hack will use Windows XP driver (a common trick to use non Vista compliant device) to install the webcam in Windows Vista and Windows 7 (x86):
- Download QuickCam 8.4.8 with driver for WinXP.
- Install WinRAR (or 7-zip) if not already installed yet.
- Open the setup installer qc848enu.exe and unpack its contents to a folder. Alternatively, right click on qc848enu.exe and select “Extract to qc848enu\” option.
- Insert or plug in the Logitech QuickCam Messenger to a USB port if not already done so.
- An “Driver Software Installation” icon in systray (notification area) should appear, which will pop up detailed message if click. It should fail, and “Add Hardware Wizard” dialog window will appear. Choose to install the driver manually by instructing the Wizard to locate and look for the web cam driver inside the Drivers folder under the unpacked folder of the qc848enu.exe setup program. You can use browser button to select the folder.
- Windows Vista should grab the XP driver and install it properly.
- Download the latest version (qc1150enu) of Vista compliant QuickCam software from Logitech to install the software on Vista.
- Run the setup (qc1150enu) normally. You may need to skip the detection of webcam near the end of installation process.
However, with the release of Windows Vista SP1 and Windows 7, the trick comes out with new error. After installing Windows Vista SP1, for some users who have use the XP driver trick to use the unsupported Logitech device, or attempt to install XP driver for Logitech webcam, the following error message will appear:
The device can not be started.
And the microphone attached on the QuickCam no longer works, where the system cannot capture or hear any sound via mic on the webcam (in device manager shown as Logitech Microphone (Messenger)).
Switching to install higher version of drivers does not help either to solve the problem. And thanks to Luis, a workaround solution has been found to fix the error.
It is strongly recommended to Backup your Windows partition (i.e. with Ghost or Acronis) before executing this solution.
The cause of the Logitech QuickCam webcam error on Windows Vista with Service Pack 1 (SP1) is USB audio class driver, USBaudio.sys, which has been updated in SP1. To solve the problem that the Logitech QuickCam Messenger, Zoom, Chat, IM, Express and other unsupported webcam model cannot be used in Windows Vista SP1 and Windows 7, one workaround solution is to ‘downgrade’ the USBaudio.sys driver file located in \Windows\System32\drivers folder to an older version.
However, in normal running computer, the file is always in use, and thus locked and cannot be deleted nor moved while system is running. Use the trick below to copy and swap back to old version of the file.
- Take ownership and grant full access permission of USBAUDIO.SYS.
- Browse to \Windows\System32\drivers\USBAUDIO.SYS file.
- Right click on the file and then select Properties on the right click menu.
- Click on Security tab.
- Click on Advanced button at the bottom.
- In “Advanced Security Settings” dialog window, click on Owner tab.
- Here you will be able to see current owner (i.e. TrustedInstaller). To take ownership of the object, click on the Edit button. If UAC prompts for administrator’s password or permission to continue, enter the correct password or press Continue button.
- Additional “Advanced Security Settings” dialog will appear. Highlight the user name (for example, Administrators) in the Change owner to box that you want to assign as the owner for the object. Click OK to make the change.
- Back in original parent level “Advanced Security Settings” window, you will see the existing owner of the file or folder has changed to the user you just selected.
- Click OK button to exit this window.
- Click OK again to exit completely from the Properties window.
- The ownership is now belonged to user or user account that been selected. To assign necessary permissions to the user too, repeat step 1 to 3 to open the object’s Properties window again.
- In object’s Properties window, click on Edit button to change permissions. If UAC prompts for administrator’s password or permission to continue, enter the correct password or press Continue button.
- Highlight the Administrators or the user who wants the permissions on the object be changed in the “Group or user names” box.
If the user ID or group that you want to manage the permissions for the object doesn’t exist, click on Add button, and type in the user name or group name desired into the Enter object names to select box, and finish off by clicking on OK.
- In the Permissions for Administrators box below (or any other user name or group name you chose), click on “Full Control” under the “Allow” column to assign full access rights control permissions to Administrators group.
- Click “OK” twice when done.
Finally, replace the USBAUDIO.sys with an older version.
- First, backup the original USBAUDIO.sys (\Windows\System32\drivers\USBAUDIO.SYS) by renaming the file in USBAUDIO.sys.bak
- Find a older copy of USBAUDIO.sys and paste in \Windows\System32\drivers\.
FIND IN XP
On Windows 7 x86 i run XP SP3 version 5.1.2600.5512 (XP SP2, version 5.1.2600.2180).
Browse with Explorer your Windows XP CD \i386\SP2.cab or \i386\SP3.cab and extract USBAUDIO.sys to \Windows\System32\drivers\
FIND IN VISTA
If you haven’t remove the backup RTM files that saved by Vista SP1 setup installer, there is a backup copy of USBaudio.sys version 6.0.6000.16386 in \Windows\System32\DriverStore\FileRepository\wdma_
usb.inf_9ce240de folder. Copy this file to \Windows\System32\drivers\
- Reboot your comp and voila it works!
I don’t know if this solution works also on Windows Vista x64 and Windows 7 x64 systems. I hope someone can verify this.

The 'Add Legacy Hardware' wizard starts (mostly) automatically when you connect your webcam.
If not, you can still manually launch the 'Add Legacy Hardware' Control Panel applet by using hdwwiz.exe.
Start --> Run --> hdwwiz.exe

Installing the drivers running them under XP Service Pack 2 compatibility has made the Quickcam work under Vista. Thanks so much for the tip!
