What Causes Error 30015-4 (-1073740791)
So you’re trying to install the latest version of Microsoft Office and you get hit with Error 30015-4. Frustrating, right? The good news is this error is often caused by issues you can fix yourself without having to call tech support.
Registry corruption or missing registry keys are common culprits. The registry is like an index of all the software and hardware on your PC. If it gets cluttered or has missing entries, Office installation can fail. You may need to run a registry repair tool to fix any issues.
Incomplete uninstallation of previous Office versions is another possible cause. Leftover files or registry entries from an old Office install can conflict with the new one. Use the Office Uninstall tool to fully remove any previous versions of Office before trying to install the new one.
Error 30015-4 can also pop up if there are problems accessing the Office installation files, like if the download source is corrupted or your antivirus program is blocking access. Try downloading the Office installer again and disable your antivirus temporarily during installation.
Still getting the error? It could indicate deeper system file corruption. Run the System File Checker to scan for and replace any corrupted system files, then try installing Office again. If that doesn’t work, you may need to do a repair install of Windows which will replace system files and registry keys.
With some patience and troubleshooting, you can squash Error 30015-4 and get your new version of Office up and running. Don’t get discouraged – try the steps one by one and you’ll be back to productivity in no time! Let me know if you have any other questions.
Fix Corrupted Files
If you’re still getting Error 30015-4 after trying the usual fixes, it’s time to dig a little deeper. Corrupted system files or damaged installation files could be the culprit. The good news is, there are a couple of tools that can help recover and repair them.
First, run the System File Checker. This scans your Windows files and repairs any corruption. Open an elevated Command Prompt and type “sfc /scannow”. Let it run, then restart your PC. This often fixes Error 30015-4 and gets Office installing properly.
If that doesn’t work, try a file recovery tool like EaseUS Data Recovery Wizard or Disk Drill. These can recover damaged or deleted installation files. In EaseUS, select the drive where you’re installing Office, choose “All File Types” and “Office Installation Package”. Disk Drill works similarly; just choose the Office setup files. Recover what you can, then try installing again.
As a last resort, you may need to do a repair install of Windows to fix any corruption in the system files Office setup needs. This reinstalls Windows but keeps your files and programs intact. Go to the Microsoft website, download the Windows Media Creation Tool, and run it to do a repair install. Once it’s done, retry installing Office.
With a little patience and the right tools, you can conquer Error 30015-4. Repairing system files, recovering damaged installation files, and repairing Windows itself should get your Office install back on track so you can get back to work. Stay positive – you’ve got this!
Check Your Hard Drive for Errors
To fix Error 30015-4, it’s a good idea to check your hard drive for any errors. Your hard drive stores all your files and the Windows operating system, so if there are any issues, it can cause problems installing software like Office.
Run the Error Checking Tool
The easiest way to scan for hard drive errors is using the Error Checking tool in File Explorer. This built-in tool can find and possibly fix a range of issues.
- Open File Explorer and right-click on your main hard drive, typically the C: drive.
- Select “Properties” and then click the “Tools” tab.
- Under “Error checking” click “Check now.”
- Check the box to “Automatically fix file system errors” and “Scan for and attempt recovery of bad sectors.”
- Click “Start” to begin the scan. This can take a while if you have a large hard drive.
Check Disk Tool
For a more thorough check, you can use the Check Disk tool. This scans the entire hard drive surface for errors and bad sectors.
- Open the Command Prompt as an administrator. You can search for “Command Prompt” in the search bar next to the Start button.
- Type “chkdsk C: /f /r” and press Enter. Replace C: with the letter of your hard drive.
- Type “Y” and press Enter to schedule the scan for the next restart.
- Restart your computer. The Check Disk tool will run automatically before Windows starts. This can take an hour or more for a large hard drive.
Once the scans are complete, try installing Office again. Fixing any hard drive errors should resolve Error 30015-4 and allow the installation to complete successfully. If you continue to get the error, there may be an issue with your Office installation files or product key that requires contacting Microsoft support. But checking your hard drive is always a good first step.

- Open the Start menu and type “Command Prompt”. Right-click “Command Prompt” and select “Run as administrator”.
- Enter the following commands, pressing “Enter” after each one:
- net stop wuauserv
