I have been projecting Pte .exe files (shows) successfully for years, but for some reason that I am wondering whether any member of this forum can solve, I suddenly cannot project them anymore. Old PowerPoint sequences made many years ago project OK still. I use a Samsung Laptop which appears to be functioning perfectly, and an Epson Projector which will still project DVDs via a DVD player. I am using HDMI leads and have tested them via the TV. All sequences will still play through the TV, that is PTE ones and PowerPoint ones. What may have happened is that someone asked me to present their PowerPoint USB sequence, which still projects OK, or it may be something to do with Microsoft Updating Windows 10. I zhave spend over 12 hours trying to solve this without success, so I would be grateful of any help. Thanks in advance. John
