🖥️ CLARUS Prime for Windows computers

Download laboratory software that runs on your own computer, without the internet

Clarus LIS is software for running a medical laboratory. It works on your laboratory's computer without the internet, under a perpetual licence you move to your new computer if you replace it, and you bring over your previous program's data (Access or SQL Server) yourself.

The program runs on a Windows computer, not on a phone

Send yourself the link to this page, then open it on the laboratory's computer and download the program there.

Or download the installer on this device

🧪 A 14-day free trial with every feature, on your laboratory's real data; then you activate your licence on the same installation and your data stays as it is.

For a computer running 64-bit Windows 10 or Windows 11. The database is included in the installer. Full system requirements

The installer is not yet digitally signed. Windows SmartScreen may warn when you run it: choose "More info", then "Run anyway". Smart App Control, on Windows 11, does not warn: while it is on it blocks an unsigned installer outright and Windows allows no exception for a single program, so it has to be turned off in Windows Security, under App & browser control, before installing.

Why Clarus LIS

What it gives a laboratory, running on its own computer

🔌

Works without the internet

All daily work runs on your laboratory's computer, and the database lives on that same computer. The internet is for optional services only.

♾️

A perpetual licence that moves with you

A perpetual licence for this computer that never expires. If you replace the computer, press "Move this licence to another computer" in the program: it gives you a code to read to us, and we release your same serial for the new computer.

🔗

Analyser connection included, and a laboratory website free for the first year

Analyser connection is included, with no fee per analyser and no limit on how many: over the serial port (ASTM and HL7) and over the network (HL7 and text). With an activated licence your laboratory gets a website under its own name at yourlab.claruslis.com, free for the first year, where a patient reads their report by QR code.

🧾

Reports in your laboratory's identity

The program prints the whole report with your laboratory's logo, name, contact details and address, so no pre-printed paper is needed. It ends with three signature places: an uploaded signature or a blank line to sign by hand.

📥

Bring over your previous program's data yourself

From your previous program (Access or SQL Server) you bring over patients, visits, results, your test names and their reference ranges from inside the program, and it shows you the counts before it writes anything.

👥

Your whole team on the program

Several people work on the licensed computer, with no limit on user accounts.

Without the internet

The internet is for optional services only

Registering patients, entering and verifying results, printing reports and billing all run on the laboratory computer with no connection. When the internet is there, it adds:

As your laboratory grows

Link your laboratory's computers and branches, included in your licence

Linked, your laboratory's computers and branches work as one system: one patient file in every branch, and each branch keeps working when the internet drops.

Manage your laboratory from anywhere

You follow and run your laboratory's work while you are away from it, through a way the laboratory switches on from inside, with two-step verification.

The trial

A 14-day free trial with every feature, then you decide

System requirements

What the installer checks on your computer before it copies anything

The installer examines the computer first and tells you plainly whether it is ready. Only a genuine obstacle stops the installation; anything else is a note.

Installation and activation

From the download to your first patient

1

Run the installer on the laboratory computer

Choose the wizard's language, and accept the terms of use and the data-handling statement. The installer checks the computer before it copies anything.

2

Choose where to install and how the program looks

Pick the folder, then the dark or light look; you can change it later in Settings.

3

Leave the serial number empty to start the trial

The program then runs for 14 days with every module. If you already have a purchased serial, type it here, or activate it later from the licence screen inside the program. The installer then copies the program and the database, and creates a private database for your laboratory.

4

Open the program and enter your laboratory's details

The program opens in its own window on the same computer, and the first time it asks for your laboratory's name and details, which are what prints on every report.

5

Activate your licence when you buy

Online, from the licence screen, in a moment. If the laboratory computer is not connected, open claruslis.com/activate on any phone and enter the serial number, and the installation code and machine fingerprint the licence screen shows (the activation page calls it the hardware fingerprint). Then download the activation file, carry it to the laboratory computer (a USB stick will do) and load it with "Import activation file" on the licence screen. One serial activates one computer.

Price details

Common questions

Questions before you download

Is the program free?

No. The trial is free for 14 days with every feature, on the same edition; then you buy a perpetual licence for your computer at the price published on this page.

Does the program work without the internet?

Yes. All daily work runs on the laboratory computer with no connection. The internet is used for optional services: activation (which a phone can do instead), updates, the laboratory website and messages.

Does it run on a phone?

No. The program runs on a computer with 64-bit Windows 10 or Windows 11. If you are reading this on your phone, send yourself the link and download the program on the laboratory computer.

What happens to my data if the computer fails?

The program takes a backup every day and checks it, and copies it automatically to another drive if you name one. The backup file needs no key, so it restores on another computer.

Are updates free? Do they install by themselves?

Updates are free for life. The program checks for them by itself; downloading and installing take two clicks from you, with a copy of the previous version to go back to.

Can I bring over my previous program's data?

Yes. From your previous program (Access or SQL Server) you bring it over yourself from inside the program, and it shows you the numbers of patients, visits and results before it writes anything. From Excel and CSV files of other programs, with our team's help.

How many computers does one licence activate?

One serial activates one computer, and your whole team works on it with no limit on user accounts. Linking your laboratory's computers and branches is included: through your own routes, or through Clarus Link, available today to every copy, licensed or in its trial, both with no fee from us.
