How to Register DSC on MCA using emSigner (Troublehsooting Errors) By CS Gaurav Kumar

Dear Professional Colleagues,

Recently, MCA has updated the settings for Registering/Updating DSC on the portal.
In this Article, I will try to resolve as many problems as possible (Troublehsooting Errors).

Kindly be apprised that earlier, it was done through Java Settings and we always wondered as in which version of Java will support.

But now, like other Govt. Portals including GST Website, MCA has come up with emSigner and it has its set of settings which one should be aware of. 

System Requirements for Usage of Digital Signature Certificate

1. Desktop Browser: Internet Explorer 10+/ Chrome 49+ or Firefox 45+
2. Valid class 2 or class 3 Digital Signature Certificate (DSC) obtained from a DSC provider

Pre-requisites for installing Web socket installer

1. Windows 32 / 64 bit OS
2. Java 1.6 JRE 1.6.0_38+, Java 1.7, Java 1.8
3. Windows: Admin access to install the emSigner component
4. Any one of the following ports should be free
  •  8080
  •  2015
