System Requirements

• Operating System: Windows XP or later (Windows 7, 8, 10, 11)

• Outlook Plugin: Microsoft Outlook 2003 or later (32-bit or 64-bit)

Installation

Before You Begin

Close all Microsoft Office applications (Outlook, Word, Excel, etc.) before starting the installation.

Step 1: Download the Installer

1. Log in to your LeapFILE web account
2. Click Download the latest LeapFILE Desktop Client with Outlook Plug-in

Step 2: Run the Installer

1. Run the downloaded installer
2. Follow the installation prompts
3. After installation, the client will prompt you to log in

Step 3: Log In to LeapFILE

1. Enter your LeapFILE URL (e.g., yourcompany.leapfile.net) - do not include http:// or www
2. Enter your email address and password
3. Click Login

Once logged in, the desktop client will run in your system tray. You can now close the login window and proceed to install the Outlook plugin if needed.

Step 4: Install Outlook Plugin (64-bit)

If you're using 64-bit Microsoft Outlook (Office 2019, 2016, or Office 365), you need to install an additional plugin:

1. After the desktop client installation completes, install the 64-bit Office Plugin
2. The installer will guide you through this process
3. Launch Outlook once complete

Determining Your Outlook Version

To check if you're using 32-bit or 64-bit Outlook:

1. Open Outlook
2. Go to File → Office Account → About Outlook
3. Look for "32-bit" or "64-bit" at the top of the About window

32-bit Outlook: The desktop client installer includes the plugin - no additional installation needed.

64-bit Outlook: Install the separate 64-bit plugin after the desktop client installation.

.NET Framework Requirement

If the installation fails and mentions ".NET Framework," you need to enable it in Windows:

1. Press the Windows key, type Windows Features, and press Enter
2. Check the box for .NET Framework 3.5 (includes .NET 2.0 and 3.0)
3. Click OK and reboot if prompted

Note

An internet connection is required to download and install .NET Framework components.
