Sorry, no Webcam was found on your system

You might receive the "Sorry, no webcam was found on your system" error for any of the following reasons:
  • You don't have a webcam installed on your system.
  • You have a webcam installed, but it is not plugged in to your computer.
  • Another application is using your webcam. Close the other applications and try again.
  • Other applications might have crashed or not released the camera. Try rebooting your system.
  • Your camera might not be installed correctly. Try reinstalling your camera.
  • Yahoo! Messenger is using the incorrect camera device. Try changing the camera source.
  • Your camera might not be configured correctly. Try configuring your camera.
  • Your camera is not compatible with Yahoo! Messenger. Take the webcam compatibility test.
Where's the Contact Customer Care button? With so many improvements to Messenger since the version you're using (lots more features and reliability), we figured you're ready to move up. So get your upgrade and with the new version, rest assured if you have questions, you’ll find that friendly button on its help pages. Thanks for helping u....

Setup.exe error msg when trying to uninstall

The setup application itself is failing. You can try to reinstall the application and then remove it again, or you can get the Revo Uninstaller from and use that. Here's the link.

Web cam installation

I was having trouble to unistall it so I could get the Vista version but it was failing with this error. So after some research I found the solution by right clicking the PowerISO icon (small yellow CD icon) at the tray and selecting at the popup menu "Set Number Of Drives" to be 2 (I just had one) and it created the virtual drive (in my case H:\). You should set it to be one more than you already have, and it'll create it in seconds. Note: PowerISO is a Daemon application and there are many other ones that creates virtual drives for temporary cache files, such as Nero. Give a search on the keyword daemon and you'll find other ones. Now, after reinstalling the software it is crashing when I run Quickcam.exe. I reinstalled twice without success... any one has a clue?

hi there

i say that you are using windows xp. what we have to do is do a system restore in order to return to the time just before youve installed the camera.

if you have any softwares installed after the time youve installed the camera, those softwares are also going to be gone.

so its your decision if you want to mae a system restore ok?

here is how to so system restore.

click start>run>type restore...a window will open and double click on the " rstrui.exe". follow the prompts and select a specific time before youve installed the cam.

hope this helps.

Normal 0 Did you install the software with the camera connected to the computer? Disconnect the camera from the USB port and reinstall the software. When the program asks you to connect the camera, do so, and it should work. Hope this is of some help. Bud

Below is info for setting up Audio & Video to chat on line after you install , either Skype or a messenger program.

Web Camera’s have to be setup on the program they are to be used with. Just installing the camera on your computer does not set it up to broadcast on messengers or Skype.

Each program has Options that have to be setup in order for the Audio and Video to function properly.

A. Skype Setup:

After downloading and installing Skype set it up as follows:

  1. Go to TOOLS, then OPTIONS, and click on Audio Settings and set the Microphone and Speakers to the computer Audio Card.
  2. Then click on the Video Settings.
  3. The camera if installed properly will come up and show a picture.
  4. Then on the bottom of the page click on Save.

The camera and audio should function properly. Your friends and Family will now see and talk to you.

B. Yahoo Setup:

After downloading and installing Yahoo Messenger set it up as follows:

  1. Go to Messenger at the top left and click on it.
  2. Next go down to Preferences and click on it.
  3. Next Calling and Devices on the right and set the Microphone and Speakers to the computer Audio Card.
  4. Next go to the Test Audio section and (in blue writing) click on “Open the call setup assistant” and follow the instructions on the left window.

C. Windows Live Messenger:

  1. After you start Windows Live Messenger, expand the view by clicking on the square on top left next to the red X.
  2. Then on the Windows Live messenger window on the right side, click on “ “Show Menus.” And then click on “Show the Menu Bar”.
  3. Next go to the Menu Bar on right side, click on “ “Action.”
  4. Go to “TOOLS” and click “Audio and Video Setting” and follow the instructions.
NOTE: You audio and video shoud work. Enjoy.

When done both the Audio and Video will function properly so you can chat and see family or friends you are connected to.
Hope this helps. Bud

Error message: Another application may be using the camera

what may be happening is photoshop is still aquiring the cam in the programme although you may of finished using the software and the camera automatically associates itself with adobe. press Ctrl, Alt & Delete to get into task manager and in the applications tab look for your photoshop programme, if it is there, click end process. If not there look in processes and do the same, this should release your camera for use with other applications. If all fails you will have to uninstall the camera software and reinstall to associate it with the cam.
