Hi, @Nayeem Nizhum
Sorry you're stuck with this. Since both Word and Excel are affected at the same time, the problem is usually not the files themselves but the Office installation or its license. A couple of things worth checking that haven't been covered yet:
First, see if Office actually knows it is licensed. Open Word (even if it only opens for a moment), click your name or picture in the top right corner and sign out. Restart the PC using Restart, not Shut down, then open Word again and sign back in with the Microsoft account you used when you bought Office or Microsoft 365. Also go to account.microsoft.com/services and check that your Office or Microsoft 365 is listed there and not expired. If Office cannot find its license, it will refuse to open or edit files.
Second, test whether the files are okay. Go to office.com, sign in, upload one Word and one Excel file and open them in the browser. If they open fine there, the files are good and the problem is on your PC. If they don't, the files themselves are damaged.
Third, if a trial version of Office came preinstalled on your PC, or you have two versions of Office installed, that often breaks things. Go to Settings > Apps > Installed apps and uninstall any extra Office or Microsoft 365 entries, then restart.
If none of that helps, do a clean reinstall. Run the official uninstall troubleshooter from aka.ms/SaRA-officeUninstallFromPC, restart, then reinstall from account.microsoft.com/services. Your documents stay where they are, only the apps are removed.
If you still can't get it working, let us know what exactly happens when you double-click a file (an error message, nothing at all, the app closes right away), which Windows version you have, and whether you use Microsoft 365 or a one-time purchase like Office 2021. That will narrow it down a lot.
