Solution Steps
- 1 Press Windows key + R to open the Run dialog. Type 'sysdm.cpl' and press Enter. Go to the 'System Protection' tab, select your system drive, and click 'Create'. Name the restore point and click 'Create' again. This creates a safety net so you can undo any changes if something goes wrong.
- 2 Press Windows key + X and select 'Terminal (Admin)' or 'Command Prompt (Admin)'. Click 'Yes' if prompted. This opens an elevated command prompt with full system access.
- 3 In the command prompt, type 'sfc /scannow' and press Enter. This System File Checker scans all protected system files and replaces corrupted ones. It may take 15-20 minutes. If it finds issues, it will fix them automatically.
- 4 After SFC completes, run DISM by typing 'DISM /Online /Cleanup-Image /RestoreHealth' and press Enter. This repairs the Windows system image itself, fixing underlying corruption that SFC might miss. It can take up to 30 minutes.
- 5 Restart your PC. Press Windows key + X, select 'Shut down or sign out', then 'Restart'. After reboot, try launching the 32-bit application again. If it works, the issue is resolved.
