Can't convert XLSX to PDF using Acrobat DC
Hello
I can no longer convert an excel file into a pdf using Acrobat DC. I use the program to combine two files, a word document, and an xlsx sheet, into one PDF. Converting the word document works just fine, but then the program force quits when attempting the excel sheet. I then get this message on the excel sheet:

The only thing I've done differently is that I uninstalled Microsoft office 2007 from my computer because I use latest Microsoft office. Could this be the issue? If so, how to I fix?
