MTNL Digital certificates and CAPICOM

CAPICOM is and ActiveX control developed by Microsoft , that enables the user to access to  digital certificates in a computer via the cryptography service.

CAPICOM has been discontinued by Microsoft.It is included in the vista OS and can be downloaded for all other OS preceding windows 7

MTNL’s e-Procurement system is one such application that requires users to login using a username and password.Then the user is to use the users Digital certificate to authenticate the session and access the e-procurement system.

The problem arises while using Windows 7 to access the e-procurement system.

However Microsoft’s .NET Framework 3.5 consists of equivalent functions.

Hence installation of .NET framework 3.5 is required for systems that need the CAPICOM control for accessing digital certificates.

The easiest way to do this is use Windows Update and install all the updates.Gradually .NET framework also gets installed.
