i have made a project. and it includes crystal report for printing something. but in exe file when i click the form then its not opening with error " Cannot load file or assembly : CrystalDecsions.Windows.Forms, version /...."
What should i do now??????

That means it can't find that assembly. Do you have it installed? Where is it installed? Is it part of the GAC?

how to install that assembly????

You go here, pay them money, and install the software they give you.

Or you can get the free version here for Visual Studio 2010.
