Take it for a full cycle

The demo is the application, not a cut-down copy of it. Install it, enrol a handful of candidates, compute a result and print the sheet — on your own machine, with nobody's server in the way.

Which machine is it going on?

Take the first one unless you already know you want another. Every build is the same application — the difference is only how it gets onto the machine.

Works on Windows 10 and newer

Install it on Windows

The usual way. It asks where to put it, then adds SDMS to your Start menu and your desktop. If an older copy is already on the machine, the records in it are left alone.

Download for Windows

Or, if you would rather not install anything

Run it from a pen driveNothing is installed. One file you open from wherever you keep it. Your records sit in a file beside it, so keep the two together.Portable · 144 MB Just the folderA zipped folder. Unzip it anywhere and open SDMS inside. Nothing is installed and nothing is added to your Start menu.Zip · 206 MB

Both of these leave the machine exactly as they found it.

//What you get

Every module: admissions, results, grade sheets, admit cards and certificates.
A sample centre with one finished cycle in it, so there is something to look at before you have typed anything.
Printing, to paper or to PDF, from the same record the marks were entered on.
Your own database file, kept on your own disk, backed up and restored from the application itself.

//What it will not do

Publish results to the portal. That is a paid plan and a key we issue to a named centre.
Run a second centre's cycles on the same licence. One licence, one centre — Federation + is the honest way past that.
Report anything back to us. Nothing checks in, which also means we cannot see what you tried: if something goes wrong, you will have to tell us.

//Check the file arrived whole

Every download is published with a fingerprint beside it. One command compares them and rules out the half-finished download that otherwise looks like a bug in the application. If none of this means anything to you, skip it — nothing here is needed to install the demo.

//Three steps, then it is yours

//01

Install it

Setup asks where to put it and adds a Start-menu entry. Nothing else on the machine is touched, and no account is created anywhere.

//02

Open the sample centre

A finished cycle is already in there. Change one mark and watch the total, the grade and the printed sheet follow it.

//03

Point it at your own register

Import a CSV, or enrol one candidate by hand. If you keep the software, the file you have been working in is the file you carry on with.

It will not install, or it looks wrong on your machine?

Tell us the build, the version of Windows or the distribution, and what you saw. A person answers — and we would rather hear it than have you give up quietly.
