Office Custom.dic File Located in Windows Msapps\Proof Folder

CAUSE

If you already have a Custom.dic file located in the Msapps\Proof folder from a previous version of Microsoft Office or a Microsoft Office application, the Office version 7.0 Setup program does not create a new Custom.dic file or location. This is so you can use the same Custom.dic file, with all the words that you have added, to check spelling in your documents.

Additionally, the Custom.dic file is created in the Msapps\Proof folder if you are running a shared Windows installation when you run Microsoft Office Setup.

When you run Microsoft Office Setup with a local Microsoft Windows installation, if you do not already have a Custom.dic file on your computer, the Custom.dic file is created in the Proof folder in the Program Files\Common Files\Microsoft Shared folder (the same folder that contains the other shared applications). However, if you are running a shared Windows installation, the Custom.dic file is created in the Msapps\Proof folder in your Windows folder instead.

This behavior occurs because with a shared Windows installation, you have write access to the Msapps\Proof folder in the Windows folder (where Windows is your home folder). It is necessary to have write access to the folder that contains your Custom.dic file so that you can add words to your custom dictionary.
