FontReg.exe is intended as a replacement for Microsoft's outdated fontinst.exe
If you...
...run FontReg.exe without any command-line switches:
- FontReg will remove any stale font registrations in the registry.
- FontReg will repair any missing font registrations for fonts located in the C:\Windows\Fonts directory (this step will be skipped for .fon fonts if FontReg cannot determine which fonts should have "hidden" registrations).
...run FontReg.exe with the /copy or /move switch:
- FontReg will install all files with a .fon, .ttf, .ttc, or .otf file extension located in the CURRENT DIRECTORY (which might not necessarily be the directory in which FontReg is located). Installation will entail copying/moving the files to C:\Windows\Fonts and then registering the fonts.
- FontReg will remove any stale font registrations in the registry.
- FontReg will repair any missing font registrations for fonts located in the C:\Windows\Fonts directory (this step will be skipped for .fon fonts if FontReg cannot determine which fonts should have "hidden" registrations).
FontReg.exe is intended as a replacement for Microsoft's outdated fontinst.exe, and like fontinst.exe, FontReg.exe is fully silent--it will not print messages, pop up dialogs, etc.; the process exit code will be 0 if there was no error.
