This is my code:

 proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
        proc.StartInfo.Verb = "print";

        proc.StartInfo.FileName = @"C:\Program Files\Adobe\Acrobat 10.0\Acrobat\Acrobat.exe";
        proc.StartInfo.Arguments = @"C:\Program Files\Obrasci\PDF\Obrasci finansijskih izvestaja\Statisticki aneks .pdf";
        proc.StartInfo.UseShellExecute = false;
        proc.StartInfo.CreateNoWindow = true;

This code open my pdf file in acrobat 10, but not work with 64 procesor.
Please help me!

Works find here on my 64bit processor (I did have to change the paths, but that doesn't change the logic). You need to be a lot more descriptive. What do you mean by "doesn't work"? Does anything happen? Do you get an error message? If so, what does it say? What options are you compiling with? What version of .NET? What OS? Did you notice that you have a space at the end of the file name right before the extension?
