I get an error when installing the add-in “The program can’t start because MSVCR100.dll is missing from your computer”.

When installing the Outlook add-in you may be presented with an error message explaining that the installer has failed because an msvcr100.dll (dynamic link library) file is missing.

This file is part of your Windows installation and is typically found in the C:\Windows\System32 directory (unless of course you have installed Windows to an alternative drive).

If you encounter this problem, please check for the presence of msvcr100.dll in your C:\Windows\System32 folder. If it is missing, please navigate to the Microsoft website link below and re-install the x86 version of this file.
