Hi All!
I had this huge problem with my A4 Tech PK635M camera with Vista. What happened was, after installing the driver when I plugged in the web cam, Vista would locate the device driver and install it successfully . However whenever I turned the AMCAP software to test my cam it would show grey screen and the webcam wouldnt work. Even though Vista detected the hardware!
Diagnosis:
What happened was that Vista mistook the A4Tech webcam for a webcam by KYE called Look 312P.
Solution:
Go to control Pannel
Click on Devise Manager
Click on Imaging Devices
-Property
-Update Driver
-Browse my computer for driver software
-Let me pick from a list of devices drivers on my computer
-Uncheck 'Show compatible hardware'
-Click on Manufacturer -> A4 Tech
Next
and your done.. Restart the pc after installation and ti wROKS!!
Note:
I think you must first download the driver CamerA.zip from the A4Tech website, Install it and then follow my instructions.
Cheers from Bangladesh!
