Installation of dRofus


The dRofus software consists of two parts, the client and the web. The web solution should always work on the latest versions Chrome and Safari, and should also work on IE 11 and the latest version of Edge. For the system requirements of the dRofus client, see below.

The program has been designed and tested for the more recent versions of Windows. All functionality will therefore not be available in the older versions of Windows.

No data is stored locally on PCs, but on a server so that all users can immediately view any changes made to data. This implies a lot of data transfer by Internet – the quicker the connection you have, the faster the data is transferred. As a user, you will have to remain connected to the Internet at all times while using the program.

Ports 5432, 80 and 8180 must remain open if the program is to function properly. Certain firewalls may therefore obstruct the program. Contact your local IT Administrator if you experience problems with log in.

Other programs

All reports generated by dRofus are created as PDF (Portable Document Format). You will therefore need Adobe Reader to read and print these reports.
Adobe Reader is free software and can be downloaded from Adobe's website:

dRofus client Installation

Download the most recent version of dRofus

The most recent version of dRofus is available at all times from dRofus' website:

Please note: When there is an update, we notify you via a blue ribbon in the client.

Install dRofus

After the download has completed, you run the installation program (double-click the downloaded file entitled setup.exe) and follow the onscreen instructions.
Once this has been completed, you can start the program from the desktop or start menu.

Note that in some environments administrators must add trust to 'Nosyko AS' because we start our application from %localappdata%', not %programfiles%. The setup.exe is digitally signed by us, and the certificate can be found by rightclicking setup.exe.


The network based installer can be uninstalled from Apps & Features dialog in Windows 10, but requires admin privileges. If you do not have admin privileges you can uninstall it using the legacy method via Control Panel → Programs → Uninstall a program.

dRofus web installation

dRofus web does not need to be installed as such, as it is running in a browser, and accessing this address will always return the latest version.

To find the address, it is always possible to access the web from the dRofus client. If you have selected a room, an item or an occurrence, you will always have a choice at the top "open in web". This will always send you to the right web address.

The addresses are as follows for the different dRofus servers:


dRofus web address

Europe, Africa and Middle East (db2 server)

US ( server)

CA ( server)

Australia and Asia Pacific ( server)

Save your dRofus web link as a favorite in your browser, to easily find it again next time you need it...

The logon credentials to access the dRofus web are the same as for the client. Your access will be regulated the same way as for the client. Please note that for now, the only thing you can write to in the dRofus web, is the note field on rooms - all the rest is read only

Automatic software updates

After the application starts soon after login, dRofus will check for updates automatically, and start to download the update. A blue bar will appear after the download is complete. You can continue to work until you find a good point to install the update. Select either "restart the application now" or close dRofus and re login. We recommend that users always work in the latest release to gain access to new features and updates.

Programs that utilize dRofus for plugin or add-on ingratiation (for example Revit or Archicad) will need to be closed before the new version of the plugin or add-on fully installs. We suggest closing those applications, login to the new version of dRofus, then restart those applications.

MSI Deployment

There is an option is deploy an MSI package - refer IT administrators to Client program page.
