I recently installed directx 10 on xp it made alot of problems for me so i looked for a way to delete it, the only way I could find was to delete the directx files. I went to regedit/HKEY_LOCAL_MACHINE/Software then deleted the files. Now I cant install directx 9  and im pretty sure its because I deleted the directx folders. Does anybody know how I can fix this and get the folders back. These are the errors I got when I tried to reinstall it.

Any help would be great    

   regedit does not have files in it.  It has entries.  You should NEVER use regedit unless you know what you are doing or you have instructions on what to do.  You can really mess things up with regedit.
   There are some DirectX uninstallers on the internet.  The one I found required free login to get it.  I don't know if they work or not.  Some people insist that DirectX cannot be uninstalled.  Do a search for directx uninstall and you should find what you are looking for.
