How to write a program to automatically install a certificate file in IE?

I've developed a signed applet and have a "x509.cacert" certificate

file. During developing and testing the software, I

manually install the file in IE. Thus, I enter

"Internet option-->Content-->Certificate" and

import the "x509.cacert" file manually.

Now I'm going to release the software and hope that

users don't do the same things as me. Therefore,

I have to write a program to automate the installation

process.

Is there any way to install the certificate file

in IE automatically with programs?

Thanks
