I've had installed the AdSweep extension it worked flawlessly, but lately in chrome://extensions/ appeared the following error:

Could not load extension from 'C:\Users\Mitko\AppData\Local\Chromium\User Data\Default\Extensions\C:\Users\Mitko\AppData\Local\Google\Chrome\User Data\Default\Extensions\adbngiigihocpeghhjgnkklmkpopjfcc\1.6.17.2'. Manifest is missing or invalid.

I deleted the extension manually but the error still remains.
Any suggestions?
Thank You.

That's your problem, deleting the extension manually screws up all its references ...

I had a similar problem and in the end had to reinstall Chrome to sort it out ...

Chrome stores the information in your "Preferences" file in the Default folder. On Win7 this is:

C:\Users\<user>\AppData\Local\Google\Chrome\User Data\Default

Open the "Preferences" file using notepad and search the file for the ID matching your broken extension. Since it looks like you are using the repackaged (newest) version of Adsweep here's what you should look for in the file:

Code:

},
         "adbngiigihocpeghhjgnkklmkpopjfcc": {
            "location": 1,
            "path": "C:\\Users\\Dean\\AppData\\Local\\Google\\Chrome\\User Data\\Default\\Extensions\\adbngiigihocpeghhjgnkklmkpopjfcc\\1.6.17.2",
            "state": 1
         },

Delete the appropriate information to make the exact same select read like this:

Code:

},

This should completely remove the reference to the extension without the need to uninstall/reinstall Chrome and reconfigure. I've tested this with Adsweep and it worked perfectly.

I've also moved this thread into Chrome Troubleshooting since this is not a bug in Chrome, but more of a generic problem you were having with Chrome as a result of not using the included uninstall method for extensions.

Thank you very much

Anytime. Glad to be of help :-D
