I have simple add-in written in C# using Excel-DNA:



using ExcelDna.Integration;
using System;

namespace ExcelDNA_test {
public class Functions {
[ExcelFunction(Name = "CURRENTDATETIME")]
public static DateTime CurrentDateTime() {
return DateTime.Now;
}

[ExcelFunction(Name = "ADDTWONUMBERS")]
public static int Add(int a, int b) {
return a + b;
}
}
}


After building i get two files for add-in installation:




  • ExcelDNA_test-AddIn-packed.xll

  • ExcelDNA_test-AddIn64-packed.xll


When i install x64 version on my laptop i can not see new category in add-in options. Also the name of add-in is not loaded properly (shows file name but not add-in name). There are no errors during installation.



I tried to install it on different machines:




  • Windows 10 x64, Excel 365 x64 - fail.

  • Windows 10 x64, Excel 365 x64 - fail.

  • Windows 10 x64, Excel 365 x64 - works.

  • Windows 10 x64, Excel 365/2013 x64 - works.

  • Windows 10 x64, Excel 2013 x64 - fails (my case).


Maybe there are no libraries installed on my PC for running this add-in?

  • Do you have any antivirus running on the machine? If you're running on a corporate environment, you might have a security app blocking the add-in from being loaded

Office 2013/2010



Navigate to Control Panel -> Programs -> Uninstall a program -> Right click on Office -> Change.



When dialog opened select Add or remove features. In Office Shared Features enable Visual Basic for Applications.



Office Shared Features Dialog





Office 2016/365



In this releases Visual Basic for Applications installed by default. To install your .xll follow next steps:



In office navigate to File -> Options -> Trust center -> Trust center settings.



When dialog opened navigate to Macro settings. Select Enable all macros.



Trust Center Settings Dialog



If you upgraded from Office 2013 with installed Visual Basic for Applications component to Office 2016/365 this issue will not appear!
