I'm having an issue where I can't open up the older files from years ago on my computer. The Word (Microsoft office 2007), Excel, Powerpoint, and image files that I had on my computer for years will not open up. But anything that I created recently will open up. I can download a powerpoint file and it will open up, but the powerpoints I had from 2012 will not open up. For my word documents, I got the mswrd632.wpc conversion error. I deleted the registry entry for it based on google advice. Word opens up but all the characters are in a weird format. PDF files give me an error message when trying to open it. For images, I can see the preview of the image in my pictures folder but when i click on it, it says no preview available.
