Error in dsc

Please check Certifying Authority from which you have taken this DSC or lodge the complaint on MCA with this screenshot.

Check whether

1. Java Runtime Environment is installed properly.

2. DSC Token Drivers are installed properly.

3. Are you able to view Details of DSC Attached from Internet Explorer.

Use Adobe Reader Version 9.5.0 or Lower.

"Allow" permissions asked while file is opened.

This problem is occuring because your token driven is not installed properly,

I have also encountered this problem,

first uninstall the old driver and restart the computer, then again install and at the time of installing tick second option name something like microsoft...then this problem will be over.

It fixes your problem 100%.
