Office is indeed installed on the computer, and there are office software icons such as word and exel on the computer desktop, and when I double-click to open word or exel, the computer prompts that the file cannot be found

Hi @Ma Alkam,

If you locate to C:\Program Files\Microsoft Office\root\Office16, then double click "Winword.exe", "Excel.exe" and other Office applications, will them opened properly?

Please check if this article is helpful to you: https://www.winhelponline.com/blog/windows-cant-find-winword-excel-exe-cant-open-avast-avg/. It explains Avast Cleanup, AVG TuneUp, CCleaner Professional, or any other tweaking program on the computer may cause such issue.
