I bought a computer with windows vista home sp2 OS pre installed on it. My problem started when I installed my A4tech PK5 webcam. It doesn't seem to work. I have tried everything from installing the driver from it's CD up to downloading drivers on A4tech's website, still it won't work. The same camera used to work with my laptop with a Vista Business installed on it. I don't know what went wrong though. Please help, I need this web cam to work asap for my job. Thanks.

But is does not harm to check if your Java, Flash and Quicktime software are installed and up to date. But certainly check your DirectX software, since all video applications, including webcams, use DirectX for video processing. Try downloading the latest DirectX version and install it (Windows XP: DirectX 9.0c - Windows Vista: DirectX 10). http://windows.microsoft.com/en-US/windows7/Which-version-of-DirectX-is-on-your-computer Hope this helps.

try searching for the correct driver through the A4 tech web site: http://www.a4tech.com/downloads.asp

if you are using at least XP SP2 or SP3, the OS can usually recognize the camera automatically and load the native drivers.

You have not mentioned the Operating System. here is the link to download the drivers and install it ( till XP ). For Vista and Win 7, the Drivers are inbuilt ( pre-loaded in the Operating System )

windows encounter a problem installing the driver software for my device kindly help me to install my webcam.

Hi tess,

Does your webcam come with a CD on the package? This maybe the driver that your PC is requiring if your OS is not yet Windows 2000 professional or Windows XP or Vista. Please insert the CD run the installer. You may need to restart your PC after the installation process is complete and you can try using the camera again.

Buy new web-cam that supported with 32bit or 64bit Vista OS

unplug the webcam and try uninstalling the driver first then reinstall with this driver http://www.a4tech.com/ennew/driver/CameraA.zip
then restart your PC and plug your webcam again.

It should run on WinXP SP2, Vista ang 64 bit

I also have the same problem, I've just upgraded my OS from XP SP2 to Vista Home Premium Edition and my A4TECH PK-750MJ won't work anymore but in my previous OS which was XP SP2, it was just a plug and play, no driver was needed, unline now, drivers were installed but it's still looking for the .inf file something. Please help! Thanks!
