How to setup your workstation for processing

This tutorial describes, end-to-end, the steps to setup a workstation for data processing.

Workstation minimum specs

The workstation can be a desktop computer or a laptop, as long as the minimum specifications are met.

  • Operating System: Windows 10 or 11
  • CPU: i7 minimum
  • RAM: 32GB minimum
  • Storage: SSD 500GB minimum
  • GPU: NVIDIA or AMD with 4GB of dedicated RAM minimum

To reduce the computation time and optimize point cloud rendering, workstation specifications can be higher than the one mentioned above. While we recommend asking a specialist to get the best out of your workstation, here a few pointers about hardware specs.

  • A better CPU (higher frequency, faster cache and memory) is the most important as PPIMMS runs mainly CPU-based computations.
  • Having the latest SSD technology and fast peripheral access is also great as PPIMMS reads and writes data on the SSD drive.
  • Except if you wish to run parallel computation (several instances of PPIMMS opened), a large RAM is not needed. Moreover, running parallel computation makes sense only if your CPU workstation can handle it.
  • A better GPU, with more dedicated RAM will improve navigation and rendering of the point cloud in the PPIMMS viewer.


Depending on your purchase, 1 or 2 software will be used:

  • PPIMMS is the main software. Among other it does trajectory computation, loop closure, GCP insertion, colorization, filtering, etc.
  • Qinertia is used for differential PPK GNSS related topics. 

Both software can be installed on several computers at a time but both software can only use the license on one computer at a time. Their licensing differs (fixed vs float). Please read carefully the section below.

Licensing format

PPIMMS license is a fixed license attached to a workstation. There is however the possibility to change the license from one workstation to another every 7 days. If done more often, the licensing server will identify it as a fraud and block your license. You will then not be able to use the software. If this happens, please contact the support.

Qinertia is a floating license. Within an organization, every time a user logs into the software, she/he takes over the licensing token. If other users were already using it, they will be ejected from the software.

PPIMMS setup

Installation file download

Download the .exe file (at this link) to install the software. Should this not be the latest version, you will always be able to upgrade it later from the interface in PPIMMS once installed.

Software installation

Right-click on the .exe file and “Run as administrator”.


Should a warning appear, click on “More info” then “Run anyway”.


On “Select Setup Language” choose your preferred language (English of French).


Click “Next” on the homepage of the setup application.


Read and accept the license agreement. Then click “Next”.


Choose your program installation folder in Windows (C:/Program Files/Viametris/PPiMMS2 by default) and click “Next”. Should it not be your first installation, a pop-up window will appear. Click “Yes”.


Choose your Start Menu preference, then click “Next”.


Choose your desktop shortcut preference, then click “Next”.


Click “Install” to start the installation.


Once completed, select both “View the Change Log File” and “Launch PPiMMS2”.


The Changelog will open in your default web browser. This file (also accessible from the software dashboard) presents the functionalities, bug fixes and other software manipulation for each release. It is important to consult them after each new release.

Working directory setup

Once PPIMMS launched, a pop-up window “Set Working Directory” appears.


We recommend you to create a folder /PPIMMS on your fastest SSD drive and select it.


Click “OK” to complete the selection.


A pop-up window “Product Registration” will appear.


You will need to provide the license number that you were given at purchase.


This number can be found on your delivery slip. It should have the following format: PPIMMS-xxxx-xxxx-xx.


Click “OK”.


The software will inform you that it needs to access the internet to verify your license. This will be done every 24hours when opening the software. During these time period, you can work “offline”. Click “OK”.


A pop-up window will appear notifying iMMS/iMS2D/iMS3D of the software compatibility. Select “Do not prompt again” then “OK”.


The software will open. It is ready to be used.



GPU software settings

To make the best of out PPIMMS, ensure that it is using your high-performance NVIDIA/AMD GPU.


To do so, open the Windows settings.


Then go to System -> Display -> Graphics.


Select “PPiMMS64” then click on “Options”.


Select “High performance”. Click “Save”.

Qinertia setup

Installation file download

Download the .exe installation file at this link.


Click on the latest link below “Downloads”.


Click on “Download Qinertia (Windows)”.


Software installation

Once downloaded, right-click on the .exe file and then “Run as administrator”.


The setup wizard opens. Click “Next”.


Read and accept the License Agreement. Then click “Next”.


Select the installation folder (by default C:/Program Files/SBG/Qinertia) then click on “Next”.


Choose your shortcuts preferences, then click “Next”.


Click on “Install”.


Once installed, select “Launch Qinertia” then click on “Finish”.


Qinertia will open. A login pop-up window will appear asking for your Qinertia account credentials. You will first need to create an account and validate your license (as described in the next section) before inputting your credentials.


After your purchase, you or your administrator (email given to SBG Systems for the account creation of your company) has received an email. Spams to check if necessary.

This email contains a license number and asks you to create an account. Click on the link for account creation, then click on “Sign up here”.

Follow the steps for your account creation.

Navigate to “Licenses”. On the top right, click on “Activate”. Provide then the license key number from the email and click “Activate”. Your Qinertia account is now setup and you are able to log into the software. Note: it is possible to create users from “My Organization”.

Go back to Qinertia. Provide your credentials. Qinertia dashboard and functionalities are now available.
