I got my Dell desktop about 3 years ago and got Office 365 with it. I have recently encountered an error message (see attachment) which causes Word or Excel to close and I lose any unsaved work.
I Googled this message and the results said I should right click on the program executable and go into the compatibility settings. I tried this and I am not sure exactly what the settings should be to prevent the error from happening. But I made some changes and then tried opening a couple of documents and I still get the error.
At first it seemed to affect documents that I have had for some time and maybe Office has had updates and doesn’t like these older documents. I tried copying the data to Google Docs, then back to new Office documents and saved under new names. They still get the error. I also made a new blank Word document and wrote 2-3 pages, with no error, then yesterday I opened that document and I got the error.
I rarely use Powerpoint and never use Access but I do use Publisher every other month for a newsletter and I worry that this problem will happen there too.
