Problem with data report with landscape format.

Hi,
I want to make my data report in landscape. I refer to this article, http://support.microsoft.com/kb/198901/EN-US.

I already registered the PageSet.dll..but still error,
this is the error,
"User-defined type not defined"

i also tried another solution by downloading latest service pack..but it doesn't work. If i click on setupsp6.exe..nothing happen..do you know why?

any idea? thanx in advance..

Can we see your relevant code? On what line in your code does this error occur if you run in debug mode?
