Error while working with Automatic Updater Component in wyb

When I click "Check For Updates" in my application I am getting an error as "Failed to create updates" When I click "View error details" I am getting the error quoted below. Error trying to save file: Error downloading "http://pradeepkumar.net.in/updates/wyserver.wys": The remote server returned an error: (404) Not Found.

Please help me in solving the issue.

Does the file actually exist on your server? Also, are you using IIS? If so see this: Why do I get a "404 not found error" when downloading wyserver.wys?

Tell me if this helps.

I have referred the link you gave.I am not using any IIS in my system.I updated the properties of update & server files from .wyu and .wys to .zip.All the files are present on server.But still getting the same error.Can you help me out in solving the issue

I just tried downloading the file link you posted (http://pradeepkumar.net.in/updates/wyserver.wys ) in my browser and it shows a 404 error. This means it doesn't exist on your server (at least not in that folder). Carefully recreate the "updates" folder and reupload the wyserver.wys file.

Then try it again.
