Running a DSC on Windows 11
A certificate that worked for years stops the week after a new laptop or a Windows update. The certificate is almost never the thing that changed.
Why this happens so consistently
Government portals in India were built over many years, and some of the signing components they rely on are older than the operating system you are now running them on. Windows 11 is stricter about drivers and about what a browser may talk to, and browsers have moved on from the plugin technology several portals were originally designed around.
The result is a predictable pattern. New laptop, or a feature update lands, and suddenly the token is invisible or the portal's signing step does nothing at all. Nothing is wrong with the certificate — the layer between it and the browser has changed underneath it.
This matters most if you bid on tenders, because the day you discover it tends to be the day a tender closes. If you have just changed machines, test your signature on the portal before you need it, not when you need it.
What to work through
Install the current driver, not the one that came with the token
The disc or download from when you bought it may predate Windows 11. Get the latest version from the token vendor or your certifying authority.
Uninstall cleanly before reinstalling
Remove the old middleware, restart, then install. Layering a new driver on a broken one leaves the broken parts behind and produces symptoms that look like new problems.
Check what the portal actually needs
Some portals still expect specific components or a particular browser. The portal's own help page is the authority here, and it is worth reading before changing anything on your machine.
Run the browser as administrator once
Some signing components need elevated permission the first time they register themselves. If signing fails silently with no error at all, this is worth trying.
Check whether antivirus is blocking the signing helper
Local signing helpers behave in ways security software finds suspicious. If you see it being blocked, allow that specific application — do not disable your antivirus, whatever any guide tells you.
Keep one machine that works
For anyone who bids regularly, this is the practical answer. A machine you do not upgrade casually, where the signing setup is known to work, is worth more than any troubleshooting guide on the day a tender closes.

Common questions
Still stuck? Send us the error
We fix these every week and we do not charge for a look. Send a screenshot of the exact error on WhatsApp along with your Windows version and browser. Most of these turn out to be a five-minute fix, and it is worth ruling that out before anyone sells you a new certificate.
