Macabacus and Microsoft (for the most part) no longer support Internet Explorer 10 and prior versions. Please consider upgrading your browser.
For the most part, Macabacus installs just like any other Windows software. However, if you are having problems with installation, please follow the steps below carefully.
Sign into Windows as the end user, not an administrator (unless the administrator is the end user), before installing Macabacus.
Download the installer named
Macabacus20XX.exe. Verify that this file name corresponds to the Office version installed on your PC. For Office 365 installations, the installer should be named
Run the installer. Request IT support for an "over-the-shoulder" installation if you do not have privileges to install software on your PC.
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 the applicable link below and install it.
Microsoft .NET Framework (version 4.5 or later)
Microsoft Visual Studio 2010 Tools for Office (VSTO) Runtime
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.
If an administrator performs an "over-the-shoulder" installation for you, sign out of Windows to complete the installation.
Macabacus may prompt you for an email address upon starting Excel, PowerPoint, or Word. Enter either (a) the email address of an authorized user to activate Macabacus, if you have already purchased a subscription, or (b) the email address you expect to use to manage your subscription if you later decide to purchase Macabacus to initiate your free trial.
You can activate Macabacus at any time using these instructions. If you are a corporate user and your email address is not recognized when you try to activate, ask your Macabacus account administrator to configure your access.
If you do not see the Macabacus tab in your Office applications after installation, please this troubleshooting guide.
Complete steps 1-4 above 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.
If you require the
.msi file packaged in the
.exe installer, perhaps for silent installs, follow these instructions:
%temp%in the address bar and hit Enter.
Macabacus 20XX.msifile you are looking for.
.msifile to another location before closing the installer dialog.
.msiwill be immediately deleted from the Temp folder.
There are also other methods to extract the
.msi, including third party software and Windows' command line prompt.
When you install Macabacus, the registry keys that instruct Office applications to load Macabacus add-ins upon start-up are created under your
HKEY_CURRENT_USER hive at:
If you log out of the Citrix "box" and then log in as another user, Macabacus should still be installed. However, the necessary registry keys will likely be missing from that user's
HKEY_CURRENT_USER hive, and Macabacus add-ins will not load for that user. Therefore, when deploying Macabacus in a terminal server environment, ensure that Macabacus is installed in the logon script, or otherwise ensure that the necessary registry keys are present in the user's
When Symantec Endpoint Protection ("SEP") blocks installation of legitimate software, Symantec calls this a "false positive." Symantec customers should report false positives at https://submit.symantec.com/false_positive/ and contact Symantec for futher assistance with installing Macabacus and/or disable or relax SEP restrictions. There is nothing wrong with Macabacus or its installer, and we have no control over the quality of SEP.
Uninstall Macabacus via Windows' Control Panel just as you would any other Windows software. To support updating your Macabacus software without losing your settings, uninstalling does not remove the folder
C:\Users\%USER NAME%\AppData\Roaming\Macabacus and certain registry entries (e.g.,
HKEY_CURRENT_USER\Software\Macabacus). Remove these items manually, if desired.
After uninstalling Macabacus, you may receive a message upon starting Excel that Macabacus.xlam could not be found. This is because Excel remembers that Macabacus.xlam was loaded when Excel was last open, and now Excel cannot find it. To resolve this, open Excel's Add-Ins dialog and select the "Macabacus" list item. When prompted to remove Macabacus, click Yes. You should no longer receive this message after restarting Excel.
This documentation refers to Macabacus version 8.11.12. Some features and descriptions of these features may not
