Depending on your operating system and computer configuration, you may require administrative access in order to install FCS Express.
It is important that if you are installing as an Administrator, but are going to be using FCS Express as a non-administrator, you should run FCS Express the first time as the non-administrator. Running FCS Express the first time as an Administrator will create certain files that the non-administrator will need to modify, but Windows will not allow the non-administrator to do so because the Administrator owns the file.
In short, run the installation program as the administrator if required, but do not run it as the administrator unless you will always be running as administrator.

| 12. If this is the initial installation of FCS Express on a Mac, the Configuration File Setup Wizard should appear. Proceed to the next section to configure FCS Express on your computer. | ![]() |
| 1. Run the installation program. Press Next on the introductory screen. These instructions make the assumption that FCS Express is being installed from a client computer to an app server or file share. However, a network license for FCS Express can be installed directly on the app server/file share if direct access is possible. If direct access is possible, the Standalone for PC instructions apply in this situation. | ![]() |

| 4. Choose the Network license radio button. Press Next. | ![]() |
| 5. Click the Browse button to select the folder in which you wish to install FCS Express. This should be the folder on the shared drive where everyone will be able to access FCS Express. FCS Express Network should NOT be directly installed on an individual user’s computer. Press Next. | ![]() |
| 6. Review your installation settings. Press Install. FCS Express will now be installed on your computer. This may take a few minutes. | ![]() |
| 7. FCS Express Network should not be directly installed on an individual user’s computer. The application is accessed through a shortcut to FCS Express.exe that resides in the installation folder on the file share. To facilitate this, a shortcut to FCS Express.exe can be created and left within the installation folder and dragged onto the desktop of a workstation that has access to the server on which FCS Express is installed. It is through this shortcut that the application will be launched from a connected workstation. Even though FCS Express resides within the central location, the application is launched and run using the resources of the local client, not the server/file share. | |
| 8. The updating of an existing network license follows these same installation steps. The main difference is that the folder specified in Step 5 needs to specify the pathway for the root folder in which the application is currently installed. For example, if your application is installed at X:InstallationsFCS Express 7 Flow Clinical Edition, the installer can be pointed to X:Installations. You can enter the UNC pathway or click the Browse button to navigate to the root folder. If the proper network folder is specified in the pathway, FCS Express will automatically update the application files within that folder. A network license is only compatible with Windows platforms. | |

Countercodes are a licensing option that you have when using FCS Express. For a detailed description of the countercode, please click here.
A countercode is not required for 45 days after purchase. De Novo Software will only issue a countercode once we have received payment for your purchase. If you purchased using a credit card, your purchase will be approved as soon as the credit card payment is processed, which is typically as soon as we enter the order into our system.
After 45 days, the software will not run unless a countercode has been entered. Please follow the procedure described below in order to obtain the countercode. Remember that the countercode will lock that copy of FCS Express to a particular computer, so be sure only to request a countercode for the computer that you want to use FCS Express on.
If you wish to obtain a countercode before the 45 days are over, you can do so by selecting System->Enter Countercode from the File tab. The wizards shown below will guide you through the process.
