How to Fix System Error H800700C1 When Opening XLSM Files in Excel
Question details
The user needs to resolve system error &H800700C1 which triggers when attempting to run VBA macros in an Excel workbook.
- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Opening an XLSM (macro-enabled) workbook and clicking to enable editing and content.
- Observed behavior
- System error &H800700C1 appears immediately after enabling content, preventing the VBA macro from executing.
Before proceeding, note the exact version of your Microsoft Office installation and verify if the XLSM file opens successfully on a different computer to determine if the file itself is corrupted.
Repair or Reinstall Microsoft Office
System error &H800700C1 is typically caused by a corrupted VBA environment within the Office installation. Repairing or completely reinstalling Office is the most direct fix.
When Excel's internal components for handling Visual Basic for Applications (VBA) become corrupted, it fails to initialize the macro environment, throwing the &H800700C1 error. A full Online Repair or reinstallation rebuilds these necessary components.
Click the Start menu, type 'Settings', and hit Enter. Navigate to 'Apps' and then select 'Installed apps' (or 'Apps & features').
Scroll down to find your Microsoft Office suite. Click the three dots next to it (or right-click) and select 'Modify'.
Select the 'Online Repair' option in the dialogue box and click 'Repair'. Wait for the process to download and replace corrupted files.
If the repair does not resolve the error, return to the 'Installed apps' menu, select 'Uninstall', and then reinstall Office fresh from your Microsoft account.
Test with Alternative Files and User Profiles
Isolate the root cause by determining whether the error is specific to a single workbook or your Windows user profile.

Frequently Asked Questions
What does system error &H800700C1 mean in Excel?
This error typically indicates a system-level issue with the underlying VBA (Visual Basic for Applications) environment or a corrupted Microsoft Office installation, preventing macros from initializing when you enable content in an XLSM file.
Will resetting Excel settings fix the macro error?
Resetting Excel settings might help if the issue is caused by a conflicting add-in, but error &H800700C1 is usually tied to core component corruption. A full Online Repair or complete reinstallation of Office is the recommended solution.
Can I open XLSM files in safe mode to bypass the error?
You can open Excel in Safe Mode by holding the Ctrl key while launching the application. While this allows you to view the spreadsheet data by bypassing add-ins and macros, you will not be able to test or run the VBA code.
