Hi,

I am playing with this blog sample:

Excel shapes events: getting notified about user actions
https://www.add-in-express.com/creating-addins-blog/2012/02/21/excel-shapes-events/

I have .NET Framework version 4 on my computer, but the sample needs version 2.

Can we install 2 different versions of .NET Framework on the same computer, without problems?

Thanks
Leon

Hello Leon,

Control Panel | Programs and Features | Turn Windows Features on or off | .NET Framework 3.5 (you can leave subitems unchecked).

Alternatively, modify the add-in project to use .NET 4: select menu Project | {project name} Properties, switch to the Application tab and see the Target framework item.

You should have both of them installed simultaneously!
