Hello Boeunjeon,
Thank you for posting in the Microsoft Q&A Forum.
I understand you're experiencing difficulty opening Excel files via desktop shortcuts using double-click, and that you're using Microsoft Office Professional Plus 2010. Based on your description, here are a few steps that may help resolve the issue:
1: Set Excel as the Default Program
- Right-click on any Excel file (.xlsx or .xls).
- Select Open with > Choose default program.
- Choose Microsoft Excel and check “Always use this app to open .xlsx files”.
2: Repair Office Installation
- Go to Control Panel > Programs > Programs and Features.
- Select Microsoft Office Professional Plus 2010.
- Click Change > Repair.
- If the configuration doesn’t finish, try restarting your PC and running the repair again.
3: Disable Compatibility Mode
- Right-click the Excel shortcut or executable.
- Go to Properties > Compatibility tab.
- Uncheck “Run this program in compatibility mode” if enabled.
4: Check for Add-ins or Corruption
- Open Excel manually.
- Go to File > Options > Add-ins.
- Disable any suspicious or third-party add-ins.
