I'm creating an Excel worksheet in C# using Excel Interop 15. Everything is running fast on a PC that have Office 2010 on it but it gets really slow on a PC with Office 2013.
If I remove Office 2013 and install Office 2010 on the same PC, it runs fast.
Any idea? Searched the web, someone tells to use CSV instead but I can't because I'm formating my worksheet with some colours and stuff. Others said to use ADO.net, will look into that. But what bugs me is it works fine with Office 2010 ...
