error while installing NodeXL Basic

Jan 6 at 1:21 PM
Hi,

I tried a couple of times, but I couldn't succeeded to install NodeXL Basic. I uninstalled older version just the same way you mention in the earlier discussions (I mean I deleted folder with the strange name). The error is below.

System.Security.SecurityException: Customized functionality in this application will not work because the certificate used to sign the deployment manifest for NodeXL Excel Template or its location is not trusted. Contact your administrator for further assistance.

And full error report is like that:

I just solved same problem right now on my PC and the solution is simple. Click on your start button and search for "internet options" or you can go through internet explorer--->Tools--->Internet options. Then on the "security" tab, choose the "Trusted sites" and click on the "Sites" button to add the http://www.nodexlgraphgallery.org/ to this address to the zone (Remember to uncheck the Require server verification (https:)....). Click ok and then go ahead to install. Remember to reset your security setting after installation. If this does not work, it means addition to the security setting stated here, you have also not added the web address to your trusted location on Excel

Hello,

we just added a new code signing certificate as the old one expired. Please download/upgrade to the latest version of NodeXL Basic https://nodexl.codeplex.com/releases/view/117659
