Upgrading Your Software

Complete steps below to update Macabacus software. You do not need to uninstall your current Macabacus version before installing updates—the newer version will overwrite the older version.

1. Sign into Windows as the end user

Sign into Windows as the end user, not an administrator (unless the administrator is the end user), before installing Macabacus.

2. Download the installer

Download the installer named Macabacus20XX.exe. Verify that this file name corresponds to the Office version installed on your PC. For Microsoft 365 and Office 2019 installations, the installer will be named Macabacus2016.exe.

3. Run the installer

Run the installer. Request IT support for an "over-the-shoulder" installation if you do not have privileges to install software on your PC. Do not attempt to manually load the installer (.exe file) as an add-in in your Office applications via the native COM Add-ins or Add-ins dialogs.

Prerequisites

The following Microsoft components (prerequisites) are required by Macabacus. If the installer cannot download or install a missing prerequisite for any reason, download it directly from Microsoft using the applicable link below and install it.

Microsoft .NET Framework (version 4.5 or later)
Microsoft Visual Studio 2010 Tools for Office (VSTO) Runtime

Full Office installation required

The full edition of Microsoft Office must be installed to support sophisticated VSTO add-ins like Macabacus. See our troubleshooting guide if the installer informs you that Office 2016 is not installed.

4. Sign out of Windows, if necessary

If an administrator performed an "over-the-shoulder" installation, sign out of Windows to complete the installation.
