Have you spent hours creating your PowerPoint presentation just the way you wanted to only have to use it on a different PC that did not have the same version or different fonts?
If you have Adobe Pro or a different PDF converter you can save your PowerPoint as a PDF. However, if you do not have either of those you can still save as a PDF. Go to the Save As option and select Find Add-ins for other file formats. Click on the Install and use the Save as PDF or XPS add-in from Microsoft option. You will have a link where you can install the add-in. Once the add-in you will have the option to Save-As PDF or XPS.
Once you have your PowerPoint saved as a PDF you can open it on any PC that has Adobe Reader. Select View, Full Screen (Ctrl + L) and you can view just like a Power Point slide show. Granted you will not have animation or slide transitions, but you will have the correct fonts, colors, and themes.
