Hi, I am a freelance designer and have a client that is constantly requesting PowerPoints for sales presentations. I have a huge volume of work with this client and am running the risk of loosing the contract if I cannot solve this issue.
I work with MAC and I have the latest version of PowerPoint for Mac installed on my machine (Version 15.30 - 2017).
The designs are very simple, in fact most of the slides are just pre-designed JPGs exported from InDesign and imported into PowerPoint. FYI I do not link the files, they are embedded to document. There are however also some templates that have been designed in PowerPoint so they can be edited by client. I share the files with my client through Dropbox. When she downloads the files be it either in PPTX or PPSX format she simply cannot open them. They are not recognized by her PowerPoint which runs on a PC. Initially we thought it was because she had an old version of PowerPoint installed so she updated and it still couldn't read the files. She tried opening the files on other machines including another MAC and could not open the files on any of them.
As you can imagine I am racking my brain trying to figure out what the issue is and am drawing a blank every time. I need help to solve this problem urgently as deadlines are looming. I am even thinking about purchasing a PC just for working with PowerPoint.
Before someone mentions it I have also tried creating presentations in Apple Keynote and exporting to PowerPoint and exactly the same problem!!
Can somebody please help and tell me why this is happening and how I can solve it. Thanks in advance.
