Cannot choose wallpaper, System Format Exception

[Maaria]

Hi
I'm new on the forum, looking for help and advice.

When I go Desktop-right click-Personalization-Wallpaper, it says

Unhandled exception has occurred in your application.
Index (zero based) must be greater than or equal to zero and less than the size of the argument list.

Have attached what it says next.


I tried this before:
1 - Go to this folder: %USERPROFILE%\AppData\Roaming\Microsoft\Windows\Themes\
(copy and paste that into the Start/search or Run box).
2 - Delete the TranscodedWallpaper.jpg file.
3 - Try to set your wallpaper again.
It changed the backround black instead of the picture I chose.

I also followed steps from this forum using Regedit but nothing changed.

Any advice appreciated.

Welcome aboard, Maaria
Have you tried http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html ?

If there is any system file corruption that restricts you to set the wallpaper, it will be fixed by that command .

Hey Arc, thank you for the reply.

SFC didn't find any problems after two goes. Anything else anyone could think of? I'm puzzled.

If you right click on any image and set as desktop background, does it work ?

Nope, it doesn't.
I can change my screen saver though but not the background. Is it possible to download and replace the background changer program?
