PMDG 737 600/700 installer freezes with an error message indicating that a font is being skipped

This problem is caused by the user having inadequate administrative installation privileges on the computer or by some type of antivirus software protecting the Windows root folder. Make sure you are logged in with a computer administrator account and that you temporarily disable any antivirus or other protection software before trying the installation again.

If you're still unable to get the installer to work, restart Windows in safe mode and run the installer and it should work.
