Admin Downloads

The FlowBreeze setup files above install only for the user currently logged into Windows. If you need to install for all user profiles on a system, then you should download the Admin installer below. Also, if you run the default (user-level setup) and get a Windows permissions error message (e.g., error code 26352), then the admin setup is required on your system. Click here to download the FlowBreeze Admin Setup

Vista Downloads

Due to changes in Microsoft's security policies, the code signing required for Windows 7, 8, and 10 does not work in Windows Vista. To install Spreadspeed on Vista you will need to download and install the Visual Studio 2010 Tools for Office Runtime, and then download and run the Spreadspeed installer.

PDF Help Files

The add-ins ship with integrated help files available via the Help menu, but if you prefer a PDF version you can download a copy below:

Installation Instructions

Single-User Installation

After you download the setup file, please follow these steps to install and register FlowBreeze and Spreadspeed. The trial downloads are the full version. When you order a license, you will receive a confirmation email containing a license key that unlocks any trial limitations.

  1. Save the setup file to a convenient location.
  2. Close Excel if it is running.
  3. If you have turned off User Account Control (UAC), re-enable it in the Windows Control Panel before running the installer.
  4. Double-click the setup file to start the installation. If you downloaded the zipped version, run the *Setup.exe file.
  5. Follow the prompts in the setup wizard:
    • We recommended that you use the default installation directory for security compliance.
    • Do not install the add-in to a network drive. FlowBreeze and Spreadspeed are COM add-ins, which must be installed to the local drive.

Installing Updates

Important Notice BreezeTree offers both user-level and admin-level installers for our Add-ins. Because of how Add-ins are registered in the Windows registry, both can be installed to the same system. This is not recommended and care should be taken to uninstall any previous version before running the setup file for a newer version.

Site-Wide Installation and Deployment

Site deployment: Our customers use a variety of tools for site deployment (GPO, SCCM, SCE, custom scripts, etc.), and unfortunately we cannot provide detailed technical support for each. However, we use a toolset from Add-in Express that handles the registration and loading of the add-in, and they have provided a useful set of instructions for deploying add-ins via Group Policy that many administrators have found useful: How to install a COM add-in using Windows Server Group Policy.

License key deployment: The license key can be placed in a text file, named either “FlowBreeze3.lic” for FlowBreeze deployments or “Spreadspeed.lic” for Spreadspeed deployments. This file can be deployed to the installation folder or to the user's My Documents folder.

MSI files: The setup file is a bootstrapper that checks prerequisites, sets permissions, and downloads the MSI installer. If you need direct access to the MSI file, you can download the zipped version, which contains both an EXE bootstrapper and the MSI. The bootstrapper EXE in the zipped file uses the MSI file included in the zip instead of downloading it.

User Account Control (UAC): If the user has turned off UAC, re-enable it in the Windows Control Panel before running the installer.

.NET Framework Installation

FlowBreeze requires the .NET 4.0 framework (or newer). Windows 8 comes with the .NET 4.0 framework pre-installed, and on Windows XP, 7 and Vista, .NET 4.0 is part of the recommended updates available through the Windows Update system. If you cannot locate the installation option through the Windows Update options, you can download and install the .NET 4.0 framework from the Microsoft website: http://www.microsoft.com/en-us/download/details.aspx?id=24872

Opening FlowBreeze

Because FlowBreeze is a Microsoft Excel add-in, there is no Start menu item to directly open FlowBreeze. Instead, you will need to open Excel in order to launch FlowBreeze.


Our software is digitally signed for security. The first time it loads, and periodically afterwards, Excel will validate the certificate. Usually it only takes a few seconds, but occasionally it can take longer and Excel will resume normal startup after validation is complete.

License Registration Instructions

If you have already purchased a license, please follow these steps to register the software.

  1. Open Excel.
  2. Click the “Help” drop down and select “Register” from the menu.
  3. On the registration screen, enter your license key and click OK.
    (To prevent typos, it is recommended that you copy and paste the license key into the form.

Updates and Upgrades

Major version upgrades (e.g., 1.0, 2.0, 3.0, ...) are announced via email to existing customers when they are released. Major version upgrades are free if you ordered within 90 days of the release date and are available at a discount for all other customers. Minor version updates (e.g., 3.1, 3.2, 3.3, ...) are always free. Several importants points to know about updates are:

  • You can check for updates via the Help menu.
  • The old version must be uninstalled before installing the new version. Uninstallation instructions are available in the help file.
  • The “trial” download is the full version. Your license key simply unlocks the 15 day trial limitation.
  • Your license key and customized settings are retained between uninstallation and reinstallation.

Pre-Made Flowchart Template Pack

These templates should not be used with FlowBreeze. They are offered free for anyone that wants pre-made swim lanes, but they were created before the Template Generator was added to FlowBreeze. With the Template Generator, it only takes a minute to create a custom template, and the templates are more compatible with the current version of FlowBreeze.
