Getting started part 1. Internal preview not working.

Hello,

Doing GS pt 2 at the section for internal preview of a ppt, and it isn't working. The preview function only generates an external preview, just as in the previous section. There is no option to select real time preview or anything. Earlier in the MS word part of the workbook as well, this did not work. Using pptx and docx files. Studio 2017 SR1.

 

 

Best regards,

Keenan
