| 0x80004005 | Unspecified error | Multiple possible causes | Medium |
Network-Related Activation Errors
Network issues are among the most common causes of activation failures. Office 2024 needs to communicate with Microsoft's activation servers, and any interruption in this connection will trigger an error.
Error 0x80072EE7: Server Name or Address Could Not Be Resolved
This error indicates Office cannot reach Microsoft's activation servers. The DNS resolution is failing, or the connection is being blocked.
- Check your internet connection is active and stable
- Flush DNS cache: Open Command Prompt as Administrator and run 'ipconfig /flushdns'
- Reset TCP/IP stack: Run 'netsh int ip reset' followed by a system restart
- Try switching to Google DNS (8.8.8.8) or Cloudflare DNS (1.1.1.1)
- Temporarily disable VPN or proxy connections
- Check if activation.sls.microsoft.com is accessible in your browser
Error 0x8004FC12: Trust Failure or Network Issue
This generic error often points to SSL/TLS certificate problems or firewall interference with secure connections to Microsoft servers.
- Ensure your system date and time are correct (crucial for certificate validation)
- Update Windows root certificates through Windows Update
- Check that TLS 1.2 is enabled in Internet Options > Advanced
- Add Microsoft activation domains to your firewall's whitelist
- Disable any third-party SSL inspection in your security software
- Run the Microsoft Support and Recovery Assistant
Product Key Related Errors
Product key errors are usually the simplest to diagnose—either the key format is wrong, the key doesn't match your Office edition, or it's already been used on another device.
Error 0xC004C003: The Activation Server Determined the Product Key Is Invalid
This straightforward error means the entered product key isn't recognized as valid for Office 2024.
- Double-check the product key for typos (common confusions: 0/O, 1/I/L, 8/B)
- Verify the key is for Office 2024, not an older version like Office 2021
- Ensure the key matches your edition (Professional Plus vs. Standard)
- Confirm the key is for the correct platform (Windows vs. Mac)
- Contact your key vendor if purchased recently—you may have received an incorrect key
- Use the 'Change Product Key' option to re-enter the key carefully
Error 0xC004F038: The Software Licensing Service Reported That the Product Could Not Be Activated
This error typically occurs when a retail product key has exceeded its activation limit, usually set to one or two devices.
- Deactivate Office on previous devices before activating on a new one
- Contact Microsoft Support to request an activation reset for legitimate transfers
- For organization keys, check with your IT department about activation limits
- Consider whether you need a volume license for multiple activations
- Wait 24-48 hours if you've recently performed multiple activations
Licensing Conflict Errors
Licensing conflicts occur when multiple Office installations or licenses compete on the same system. This is especially common after upgrades or when switching between subscription and perpetual licenses.
Error 0xC004F017: The Software Licensing Service Reported That the License Is Not Installed
This error indicates the grace period has expired before activation was completed, or the license store is corrupted.
- Re-enter your product key: File > Account > Change Product Key
- Reset the license store using OSPP.VBS scripts (detailed below)
- Uninstall and reinstall Office 2024 with a clean installation
- Clear any residual licenses from previous Office installations
- Check for Office 365 subscription conflicts if present
Resolving Multiple License Conflicts
When Office shows the wrong license or subscription conflicts with perpetual activation:
- Sign out of all Microsoft accounts in Office applications
- Remove cached credentials from Windows Credential Manager
- Use OSPP.VBS to list and remove all installed licenses
- Perform a clean Office installation using the Office Deployment Tool
- Ensure no Microsoft 365 apps are installed alongside Office 2024 LTSC
Volume Activation Errors (KMS/MAK)
Organizations using volume licensing face unique activation challenges. KMS activation requires proper infrastructure, while MAK keys have activation count limits.
Error 0xC004F074: The Software Licensing Service Reported That the Product Could Not Be Activated
This is the classic KMS activation failure. The client cannot locate or communicate with the KMS host server.
- Verify the KMS host is running and has an active Office 2024 CSVLK
- Check DNS for the _vlmcs._tcp SRV record pointing to your KMS host
- Ensure port 1688 is open between clients and the KMS host
- Confirm the KMS host has reached the activation threshold (5 for Office)
- Try manual KMS host specification: cscript ospp.vbs /sethst:kmshost.domain.com
- Check the KMS host's activation status with slmgr.vbs /dli
MAK Activation Count Exceeded
MAK keys have a limited number of activations. When exhausted:
- Contact Microsoft Volume Licensing Service Center (VLSC) to request additional activations
- Document the business justification for the increase
- Consider switching to KMS activation for larger deployments
- Use VAMT (Volume Activation Management Tool) to proxy-activate isolated machines
Diagnostic Tools and Utilities
Microsoft provides several tools to diagnose and resolve activation issues. Here are the most effective ones:
Microsoft Support and Recovery Assistant (SARA)
This official Microsoft tool automatically diagnoses and fixes common Office activation problems. Download it from Microsoft's support site and run the Office activation troubleshooter.
Download SARAOffice Activation Troubleshooter
Built into Windows, this troubleshooter can resolve many common activation issues automatically.
- Open Settings > Update & Security > Troubleshoot
- Click 'Additional troubleshooters'
- Select 'Windows Store Apps' (covers Office from Microsoft Store)

License Cleanup Tools
For persistent issues, completely removing and re-applying licenses often works:
- Download the Office License Removal Tool from Microsoft
- Run the tool to clear all Office licenses
- Restart your computer
- Reactivate Office with your product key
Command-Line Troubleshooting
For advanced troubleshooting, command-line tools provide detailed diagnostic information and granular control over the activation process.
OSPP.VBS Commands for Office 2024
The Office Software Protection Platform script (ospp.vbs) is located in your Office installation folder. Run Command Prompt as Administrator and navigate to:
cd "C:\Program Files\Microsoft Office\Office16"cscript ospp.vbs /dstatusDisplay current license status and detailscscript ospp.vbs /actAttempt to activate Officecscript ospp.vbs /inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXXInstall a product keycscript ospp.vbs /unpkey:XXXXXRemove a product key (last 5 characters)cscript ospp.vbs /remhstRemove KMS host name (revert to DNS)cscript ospp.vbs /rearmReset the licensing status (extends grace period)SLMGR.VBS for Windows and Office
The Software Licensing Management Tool provides additional diagnostics:
