Welcome to Justanswer.com, my name is ***** ***** I will do my best to assist you.
Ive seen this issue before and I can help you solve it.. Would you prefer to have me connect to your computer from here and fix your powerpoint file save issue in person? Or do you want me to try and guide you through the process via written support instead?
To get started, I need to know what type of computer you're using.Windows XP, Widows Vista, Windows 7, Windows 8, Or a Mac.If it's a Mac, please check the OSX version as follows.Click the apple sign at the top left of your screen, then click about this mac. And then where it says version, send that to me as a reply.
