I have created a simple Revit add-in that automatically fills in the sheet's border information based on information within an excel file. This add-in works fine in Revit 2024.1, but when trying to use it on a machine with 2024.2 installed the following error is shown.
In my code I am using Microsoft.Office.Interop.Excel to interact with Excel. My add-in is a C# Class Library in Visual Studio using .NET Framework 4.8. Any ideas on why this would work with 2024.1 but not 2024.2 would be greatly appreciated!
