NodeXL Basic Excel Template error

[GavinRayner]

I'm trying to install NodeXL Basic Template on a Windows 10 Enterprise laptop (Version 1803, OS build 17134.345) with MS Excel 2016 (16.0.4738.1000) 64-bit. There are no errors when I run NodeXLBasicExcelTemplate2018Setup.exe Then when I try to open the NodeXL template I get: "Microsoft Office Customization Installer Updating Office customization There was an error during installation. Name: NodeXL Excel Template From: http://www.nodexlgraphgallery.org/NodeXLBasicSetup/Smrf.NodeXL.ExcelTemplate.vsto

I suspect it's something to do with .NET versions? Here's what I have installed: C:\MyDocs>NET_Detector_cli.exe

Raymondcc .NET Detector CLI

Installed: .NET Framework 2.0 Service Pack 2 .NET Framework 3.0 Service Pack 2 .NET Framework 3.5 Service Pack 1 .NET Framework 4.7.2

Any suggestion greatly appreciated.

Hello Gavin,

On some systems (often in large corporations or universities) access to websites needed by NodeXL are blocked. To resolve this issue, these web site addresses can be added to a list of trusted sites.

NodeXL needs access to the NodeXLGraphGallery.org web site.

To enable access to this web site, from the Windows Start menu, search for "Internet Options" and then select "Security" and "Trusted Sites".

There is a button below the Trusted Sites menu: "Sites" - select this to add the NodeXLGraphGallery.org web site to the exception list:

The Trusted Sites dialog will allow you to enter the following web addresses: http://www.nodexlgraphgallery.org https://www.nodexlgraphgallery.org

NOTE: It is necessary to UNCHECK "Require server verification (https:) for all sites in this zone.
