installing certificate
 

In my installer i want to install (or import) one certificate is there any plugin available to do this?
Which windows command(or exe) i can use to install the certificate?

A good starting point:

You could with Delphi create an certificate import plugin.

i just want to know which sysem utility is called when i double click my certificate. Also i want to drop the window which shows its description & directly goto certificate import wizard

Use: pvkimprt

"drop the window which shows its description", is impossible with creating your own routines. There in no commandline option to do this.

You could send a message to click next by finding the window ofcourse.

Note:
Why hide the description? By showing the discription the user has better information if he realy does want to import the certificate.

But as stated before look at what secureblackbox has to offer, after intense research you will find what you need there.
