One:

Click the "Start" button and find the excel icon.

Hold down the ctrl key, click the icon and open it in safe mode. Then click "Help" and "Check and Repair" in the software interface.

Download an office antivirus tool and try to kill virus. Some viruses 360 are not as useful as it.

You can find the office→office tool in the start menu, and click Apply to restore it.

Two:

1. Start, enter regedit.exe after running, and then "run as administrator" to open the registry.

2. Find the registry path according to the following path: HKEY _ Local _ Machine \ Software \ Microsoft \ Office \ Excel \ Addins \ Bt Office ddin. BT Office Integration.1.

3. Find the LoadBehavior item and change its value to "0".

4. Exit the Registry Editor and reopen EXCEL to see if the problem has been solved.

If the office software really doesn't work, reinstall it.
