Q. When I try to install EmEditor, the "Error deleting file" message appears and cannot continue.

When you try to install EmEditor, the following message box appears and cannot continue:

Error deleting file:

Please use Disk Cleanup that comes with Windows. To start Disk Cleanup, click the Windows Start button, type "Disk Cleanup" and press ENTER. Click the "Clean up system files" button to complete delete unnecessary system files. After you finish cleaning up unnecessary files, you can restart Windows and try installing EmEditor again.
