I've had this laptop for 2 or 3 years now. It had Vista installed on it to begin with, and has Windows 7 now. Up until about a week ago my webcam worked fine. It might have stopped working before that, but I don't use it very often so I can't be sure. My laptop is a Toshiba Satellite A300 PSAG8-047013C. When I try to use my webcam with any application I get the message:

"Webcam is either disabled or has failed. Please check your webcam settings."

Before that, Windows asks me if it's okay to allow traybar.exe to make changes to my computer, which it never asked before when I tried to run the webcam software.

So far I've tried deleting and reinstalling the original software (which was made for Vista, but my webcam's always worked fine on 7), as well as trying to update it with driver_camera_chicony_TC50040800A.exe, which I got off of the Toshiba site. I've tried running this with the original software both installed, and uninstalled. All it does in either situation is start up, ask me to press a start button, then Windows asks if it's okay for the program to make changes, and then it stops doing anything. Nothing happens.

The only thing I can think of that might have made this start happening was using CCleaner to clean up the registry. I'm really not sure if that's actually it, but it's the only idea I've got. Thanks for any help you guys can give me!

Registry Cleaners are notorious for causing more problems than they solve. So it could possibly be CCleaner's registry 'clean up' that caused the problem.

CCleaner asks you if you want to backup changes to the registry before performing the 'clean up'. If you did create a backup, you can restore what CCleaner removed by running the backup .reg file. It will look something like this: cc_20111101_193105.reg

If the backup exists, I would restore it and then try reinstalling the camera software/drivers again.

Here is some good info about Registry Cleaners.

Bleeping Computer DOES NOT recommend the use of registry cleaners/optimizers for several reasons:

  • Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.

    The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.
  • Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.
  • Not all registry cleaners create a backup of the registry before making changes. If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.
  • Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.
  • The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".
Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.

I think I probably had a backup for a while, but I don't see it anymore. Probably deleted it when I didn't think anything was wrong with my computer. >.> This info is great, about registry cleaners. I won't use them anymore I'm thinking. :P Since I don't have a backup, anyone know what else I can do?

I've been using Ccleaner for years and have not made any kind of harmful effect on any of my computers. Must be another conflict on your installed softwares.

That link provided me with a different install than I had tried before. Things may have improved, but it's still not working properly. Windows still asks me if it's okay to let traybar.exe run (which it never used to do). My camera sidebar seems to be working now, but when I try to run the camera I get the message:

"Webcam driver open fail. Please restart camera or computer."

Restarting my computer doesn't seem to be working. Now all I might need is a driver update, so I'll look around and see if I can find one. Until then, anyone else know something that might help?
