OK this is probably easy, which is why I can't get it to work. I nee to download & install sevice pack 3 for autocad 2009 LDD when I do I get the following error, see picture.

Can I get a helping hand?

Go back to the place you found this SP3, did it say it was made for 2009 LDD.

I don't see it said you need it.

Did you check the Readme file on the download page?

AutoCAD Land Desktop 2009 Update 3 contains the fixes included in AutoCAD 2009 Update 3. To be able to install and use this update you must have AutoCAD Land Desktop 2009 Update 2.1 installed on your system.

Do you have 2.1 installed?

Thanks for the reply, I'll go back and look at that.
