Windows ERROR_216 is an uncommon but frustrating problem that can disrupt your workflow by preventing software from running properly. This error typically occurs due to memory addressing issues, compatibility problems, or corrupted system files. If you’ve encountered ERROR_216 on your Windows computer, don’t worry—we’ve got you covered with this detailed, step-by-step troubleshooting guide.
What is Windows ERROR_216?
ERROR_216 is a Windows system error often linked to problems with 16-bit applications, memory issues, or corrupted program files. It can arise when running legacy software or during system startup, and typically manifests with a message indicating that a specific application cannot start or a system resource is unavailable.
Step 1: Identify When and Where ERROR_216 Occurs
Before rushing into fixes, pinpoint when the error happens:
- Is it while launching a specific program?
- Does it occur during system startup?
- Is it a random error popping up during normal usage?
Knowing the context helps tailor the fix more precisely.
Step 2: Run Application in Compatibility Mode
Many ERROR_216 cases relate to older, 16-bit or legacy programs incompatible with modern Windows versions.
How to do this:
- Right-click on the application’s shortcut or executable file.
- Select Properties.
- Navigate to the Compatibility tab.
- Check Run this program in compatibility mode for: and select a previous version of Windows from the dropdown (e.g., Windows XP or Windows 7).
- Also check Run this program as an administrator.
- Click Apply and then OK.
- Try launching the program again.
Running apps in compatibility mode often bypasses ERROR_216 caused by system incompatibility.
Step 3: Scan for Malware and Viruses
Malware can corrupt system files or interfere with programs, triggering ERROR_216.
Steps:
- Update your antivirus software to the latest definitions.
- Run a full system scan.
- Quarantine or remove any detected threats.
- Restart your computer and test the issue again.
If you don’t have antivirus software installed, consider downloading reputable freeware such as Microsoft Defender or Malwarebytes.
Step 4: Check and Repair System Files
Corrupted or missing system files often generate ERROR_216. Windows has built-in tools to scan and repair these files:
Using System File Checker (SFC):
- Press Win + X and select Windows Terminal (Admin) or Command Prompt (Admin).
- Type
sfc /scannowand press Enter. - Wait for the scan to complete; it may take several minutes.
- If corrupt files are found, the system will attempt automatic repairs.
- Restart your PC and check if the error persists.
Step 5: Use Deployment Image Servicing and Management (DISM)
If SFC cannot fix the problem, DISM can repair the Windows system image.
How to do it:
- Open Command Prompt as Administrator (see Step 4).
-
Type this command and press Enter:
DISM /Online /Cleanup-Image /RestoreHealth
- Wait for the process to complete—it can take 10-15 minutes.
- Once done, reboot your PC.
This tool can fix deeper image corruption affecting system stability.
Step 6: Reinstall or Update the Problematic Application
If ERROR_216 occurs only with a particular program:
- Uninstall the application from Settings > Apps.
- Restart your computer.
- Download the latest version from the official website.
- Reinstall the program.
- Consider running it in compatibility mode as explained in Step 2.
Reinstallation often resolves issues caused by corrupted installation files.
Step 7: Check Your Computer’s Memory (RAM)
Faulty RAM or memory addressing errors can cause ERROR_216.
Test memory with Windows Memory Diagnostic:
- Press Win + R, type
mdsched.exe, and press Enter. - Choose Restart now and check for problems.
- Your PC will reboot and run tests—this may take some time.
- After completion, Windows will report if any memory issues were found.
If RAM problems appear, you may need to replace or reseat your memory modules.
Step 8: Update Windows and Drivers
Outdated system updates or device drivers can cause incompatibilities:
- Open Settings > Update & Security > Windows Update.
- Click Check for updates and install all available updates.
- Update your device drivers, especially graphics, chipset, and storage controllers.
- You can use Device Manager or visit the hardware manufacturer’s website for drivers.
Keeping your system current prevents many errors, including ERROR_216.
Step 9: Perform a Clean Boot
Third-party software conflicts sometimes trigger this error.
How to perform a clean boot:
- Press Win + R, type
msconfig, and press Enter. - Under the Services tab, check Hide all Microsoft services.
- Click Disable all.
- Go to the Startup tab and click Open Task Manager.
- Disable all startup items.
- Close Task Manager and click OK in System Configuration.
- Restart your computer and check if ERROR_216 persists.
If the error disappears, enable services/startups one-by-one to find the culprit.
Step 10: Contact Support or Consider System Restore
If none of the above steps work:
-
Use System Restore to revert your computer to an earlier point when it worked:
- Go to Control Panel > Recovery > Open System Restore.
- Choose a date prior to the error’s appearance and follow the prompts.
- Alternatively, contact the software vendor or Microsoft Support for specialized help.
