MS Office Repair

When exporting to Excel, I get the error message "Microsoft Excel is not installed on this computer" although Excel is installed. Why?

First, try to fix this with DLInstaller.exe as described in FAQ 2274. If that fails, you can try the following procedure.

Go to Apps & Features in Windows → find MS Office and click Edit. In the next dialog box, select Quick Repair. If that fails, select Online Repair.

If this workflow is also unsuccessful, you should reinstall Excel.
