How to Fix "Digital Signature Certificate (DSC) Not Found" Error on eproc2.bihar.gov.in

Contractors bidding on the Bihar Government e-Procurement portal (eproc2.bihar.gov.in) often face a roadblock at the final step: the "DSC Not Found" or "Applet Blocked" error. Since Bihar recently migrated to the updated eProc 2.0 system, it strictly requires a Class III DSC. If your token is plugged in but the portal can't read it, the issue is usually your Java or driver configuration.

The Ultimate Step-by-Step Fix

1. Check Your DSC Class: Ensure you are using a valid Class III DSC. The older Class II DSCs are being phased out on the new portal.
2. Install 32-Bit Java (Crucial): The portal's signing components rely heavily on 32-bit Java architecture. Even if your PC is 64-bit, uninstall your current Java and install the latest Java Development Kit (JDK) 32-bit version.
3. Update Token Drivers: Press Win + X and open Device Manager. Look under "Smart Card Readers." If there is a yellow warning icon next to your eToken/ProxKey, right-click and update the driver.
4. Configure Java Security Settings:
   • Search for "Configure Java" in your Windows search bar.
   • Go to the Security tab. Check the box for "Enable Java content for browser and Web Start applications."
   • Set the security level to "High" (Do not set it to Very High).
   • Click Edit Site List and add: https://eproc2.bihar.gov.in
5. Browser Settings: Use Google Chrome (Version 97.x or above) or Microsoft Edge. When you click "Select Certificate" on the portal, allow any Java pop-ups to run. Your DSC will now appear successfully.
