Ive tried uploading the dls System.Web.Extensions version 2.0 NOT Version=1.0.61025.0
And it stills gives me an error.. Can i somehow change so it will look for 2.0 version of the dlls not the 1.0.61025.0 which i dont have? Or can i download the 1.0.61025.0  dlls of system.web.extensions and System.Web.Extensions.Design dlls from somewhere?

Thanks !

are the web servers configured the same? if it works in the dev, and not in the production, then I would think the server is confgured wrong. If it is IIS, then you may need to change the asp.net config of the website.

Its configured I use the same server software on the webserver as on the dev. It just wants an old version of the system.web.extensions which i appearnlty have on the dev server but not on the webserver. I have searched for it on the dev server but with no luck

Did you have to install the ajax extension packages 1.0 on the production server?  If so, how, the default location?
