[Fixed] e-Procurement website Login Problems at E tendering Site

I have been filling Online tenders for longer time, but recently i have came across A Problem where i was not able to Login button of DCS after First login,
even i had installed Latest version of Java,Latest Version of Browsers , and DCS drivers and Pen Drive was correctly installed. I have checked everything into my computer but nothing worked,

After some research i have found that All Latest browsers have dropped support for Java plugins( NPAPI support ) due to security reason. If your FireFox version is Newer then 52.x, Mircorsoft edge, Google chrome 45.x or newer then you can not use eprocure.gov.in or any state govt’s e procurement website.


List of effected Govt E tendering websites due to this.



And many Other Govt Websites.

How to check if your browser not supporting Java?
If you want to check whether your browser supporting Java or not then visit


  1. First make sure you have installed Java JDK 8,

Download and install from here http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

2) insert DCS and install its software.


Open Internet Explorer and Use the site. It should work. If you are u unable to find it then

Press Windows+R to enable Run, type iexplore and tap OK. Internet explorer will be launched.

With it the login problem will be solved,


If it does not work in Internet explorer then Download older version of Mozilla  Firefox 40.

    Facing same issue, after download Fire fox 40 & Java JRE 8.261 problem not solved

    tried everything, like fresh installation of java and changing security setting but same error
    Java Run Time Environment (JRE) 1.8 or above should be installed.
    DSC drivers should be installed from the resource CD.
    The DSC smart card / e-Token must be plugged in with the system’s USB port / smart card reader.

      Try installing exe OR mai file from your DCS token

    I have two laptops. Same Login button doesn’t appear problem. In one Laptop, it works only in Internet Explorer (it doesn’t work in chrome or firefox). In the other Laptop, it doesn’t work in any browser. There seems to be no solutions at all. But there is a trick, which I am unable to figure out. Very frustrating. I had problem in putting DSC in annual forms of LLP. I had to approach third party to help and they gave me the .pdf form which worked perfectly. The entire system is designed so that road-side Third Parties get tax-free business.

      That may be because your browser’s auto update is on. You should stop auto update from Menu > Options > General > Firefox Updates > Never Check for updates.

    Dear Sir, Thank you for these instructions. I was able to successfully enable:
    – I used Firefox (50.1). 64 bit firefox does not support Java so please use 32 bit firefox. You can download from: https://ftp.mozilla.org/pub/firefox/releases/50.1.0/win32/
    – I downloaded 32 bit Java (Java 8u300) from java.com website
    With these and using Sir’s instructions above, it started working.
