adobe acrobat pdf link cann't work on windows form

[C# Programming]

I am using C# and have created a regular Windows form. I have used COM and registered AxAcroPDFLib.AxAcroPDF. Here is my code;

axAcroPDF1.LoadFile("myfile.pdf")
axAcroPDF1.Show();
MessageBox.Show("Showing...");

This works fine. But, just like the browser, but PDF file links can't work. I have the full version of Adobe Acrobat installed, Standard 8.0. I also have the Pro. version 7.1.0 on another PC. When I click on link ,Its can't open link URL.


Thank you for any help. please.
