Generating Excel - missing theme1.xml

Oct 4, 2016 at 3:50 PM
When I generate .xlsx file, xl\theme\theme1.xml file is missing. I don't want to code to zip it into the file and I was wandering is there any way to force epplus to create this file inside the excel file when creating it? I need this because 3rd part software converts this file later on and it asks for this xml.
