This error usually occurs when:

• Your presentation is too large - compress media and reduce image quality
• You have too many applications open - close other apps
• Your computer lacks RAM - close unused programs and restart
• You're using an old PowerPoint version - update to Office 365

Will repairing Office delete my presentations?
