This can be fixed using the following:

  1. Click on the Start button, type regedit and then press enter
  2. Click Yes on the UAC message
  3. Browse to HKEY_CURRENT_USER\Software\Classes\.html
  4. Right click the value for the .html key and select Modify
  5. Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)
  6. Click Ok
