After creating Office Add-In template project, on execution I am getting an error which says application isn't installed in this computer.
What should I have to install? I ave already installed Office Tools from Visual Studio installation.
I have Visual Studio 2017 Project Type was : Office Add-In ( PowerPoint Web Add In) Office version is : 2007
A Web Add-in (which uses the Office JS APIs) only works with Office 365. You'd need to create a VSTO project for an Add-in that runs in any earlier version of Office.
