When accessing the website for downloading the VyNDEX Excel Add-in through a Web browser, the following message appears and the installation fails.
“The following Microsoft Office solution cannot be installed due to a general installer error: VyNDEX.vsto.”
The installation fails because Microsoft Excel 2016 doesn’t include “Visual Studio 2010 Tools for Office Runtime” that is necessary for downloading VyNDEX.
When using a PC on which Microsoft Excel 2016 is installed, you have to download and install the runtime from the following Microsoft’s website before installing VyNDEX.
Visual Studio 2010 Tools for Office Runtime
