How to Fix Office Apps Closing Randomly with Cscript Error 0x1A8
Question details
Microsoft Office applications unexpectedly close during use, and checking the licensing status via cscript returns an error code 0x1A8.

- Product
- Microsoft Office
- Device & OS
- Windows
- Scenario
- Using enterprise volume-licensed Office applications on a work computer where the connection to the KMS server or licensing service is interrupted.
- Observed behavior
- Office apps crash or close randomly. The OSPP.VBS script returns error 0x1A8, and Windows Event Viewer logs Volume Shadow Copy Service and Security Center errors indicating a system shutdown is in progress.
Since this error typically occurs on enterprise-managed work computers, ensure you are connected to your company's network or VPN, and be prepared to contact your IT administrator to check server permissions.
Review Windows Event Viewer for Conflicting Services
Check the Event Viewer to identify underlying system, antivirus, or shutdown events that are forcing the Office licensing service to close.
The random closing of Office apps often stems from system services crashing in the background. Investigating the Event Viewer around the time of the crash can reveal if the Volume Shadow Copy Service or security software is malfunctioning.
Press Win + X on your keyboard and select 'Event Viewer' from the Power User menu.
In the left pane, expand 'Windows Logs', then click on 'System' and 'Application' to view recent system events.
Scroll through the logs to find Error or Warning events that match the exact time your Microsoft Office application closed unexpectedly.
Check for errors mentioning 'Volume Shadow Copy Service', 'CEventSystem', or 'AntiVirusProduct'. Document these errors to share with your IT department.

Verify KMS Server Connection with Your IT Administrator
Work with your IT support team to ensure your computer can successfully communicate with the enterprise KMS licensing server.
Switch to WPS Office to Avoid Complex Licensing Errors
If volume activation issues, KMS server downtime, and random app closures are disrupting your productivity, consider switching to WPS Office. It provides a highly compatible, hassle-free alternative without the need for complex enterprise licensing infrastructure.
- 1. Download WPS Office: Visit the official WPS Office website and download the free installer.
- 2. Install the Software: Run the installer to quickly set up the application on your computer without complex licensing configurations.
- 3. Open Your Files: Double-click your existing Word, Excel, or PowerPoint documents to open them seamlessly in WPS Office.

Frequently Asked Questions
What does Cscript Error 0x1A8 mean in Microsoft Office?
This error code indicates a communication failure with the Key Management Service (KMS) volume activation server. It means your Office installation cannot properly contact the server to verify its enterprise license status.
Why are Volume Shadow Copy Service (VSS) errors appearing alongside my Office crash?
The Office licensing service relies on several core Windows services to function. If a system process, unexpected shutdown event, or third-party antivirus disrupts these services, it can simultaneously trigger VSS errors (like 0x8007045B) and force Office apps to close.
Will reinstalling Microsoft Office fix the random closing issue?
No, reinstalling Office typically does not fix this specific issue. Because the root cause is usually a blocked network port (port 1688), a disconnected KMS server, or an aggressive antivirus policy, a clean installation will still fail to activate and crash.
How can I check my Microsoft Office activation status manually?
You can check your status by opening Command Prompt as an administrator, navigating to your Office installation folder (for example, Program Files\Microsoft Office\Office16), and executing the command 'cscript ospp.vbs /dstatus'. This will return your current licensing details and any associated error codes.
