Pk-653 compatible driver with window 7

you can click on this link: Windows 8 compatibility for A4Tech PK 635M Webcam model

I noticed that there is no Windows 7 specific driver for this older camera. This can be problematic as the older XP drivers sometimes work and sometimes do not work in Windows 7 32 bit or 64 bit.

Good luck on this compatibility issue with Yahoo Messenger. Maybe try Skype or Windows Live Messenger for video chat.

What is your operating system. If you upgrade your operating system to windows 7, your driver will be outdated and needs driver compatible with your windows 7.

Try updating the cam drivers A4tech digital PK-333E drivers (Supported OS: XP, Vista, Windows 7, MAC10.4.8) from A4 Tech Site. Read the installation instructions carefully.

Hope it helps.



.

Try running the installer in compatibility mode (Vista or XP).
Alternatively, you can try to find a compatible webcam driver.

If it worked fine in a previous OS - try running it in Compatibility Mode
Right click on the webcam desktop icon and select 'Properties' click 'Compatibility' tab and select CM and the OS from the dropdown box
Click Apply and OK

Window 7 will NOT play nice with anything other than the most up-to-date-hardware, you simply will have to get a web cam that IS supported by Win 7. You may like to try this-->>
It may or may not work, but try installing as Administrator and setting the program's EXE into "Compatability Mode for XP SP2",and also, running as Administrator. Windows 7 just doesn't want to support any hardware over like a year old... Drivers are a HUGE issue. Especially for older stuff. Compatability Mode is one way round it but not always. Also you will have to set to OFF digital Driver signing at bootup press F8, and at the bottom you will see driver signing.... EVERY TIME you boot you MUST set this OFF, or it will simply not work, thats if it does install anyway. You MUST have it OFF to install as well.

Download the software that worked with your previous OS
Right click on the webcam icon and click 'Properties'
Click the Compatibility tab
Check the box to run in CM and enter the OS in the dropbox
Click Apply and OK
You may need to check additional boxes under 'Settings' but that will be trial and error
Any feedback will be useful.

Hi,

Just plug the webcam in and windows will automatically install the drivers, if it asks for the drivers just insert the disc, when you do this windows will auto play the CD so just shut down the auto install program and leave the disc in the drive and carry on with the driver installation manually.

Here is the driver download as well: http://www.a4tech.com/ennew/download%20driver.asp
