How to check if .net interoperability for excel is installed
I am "using" Microsoft.Office.Interop.Excel in my C# code.
I want to use the code related to Microsoft.Office.Interop.Excel only if PIA for Excel is installed on that machine.
But, I get exception when I call that function (which uses Excel Interoperability)
Why am I getting exception even if that code actually isnt getting called? How to workaround this issue? i.e to use Excel PIA only if it is installed.
Thanks
