# Set a registry key for font linking

To be sure that font linking works in Windows 7 Professional SP1, it is recommended that you use Tahoma or Microsoft Sans Serif fonts in your FactoryTalk View Machine Edition application.

If you want to use language switching with another font, you will have to add a registry key for that font. You can link the base font to all the fonts that are linked to Tahoma or Microsoft Sans Serif.

The registry key that is set using these directions only exists when fonts that support font linking are installed. When you install a new Windows language or language group, part of the process installs the fonts and enables font linking.

## To link a base font to multiple fonts

1. From the Start menu, select Run.
2. In the Run dialog box, type regedt32 and press OK.
3. Select the window titled HKEY_LOCAL_MACHINE on Local Machine.
4. Navigate to C:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts.
5. In the right pane, select the value for Tahoma or Microsoft San Serif.
6. From the Edit menu, select MultiString.
7. In the MultiString Editor, select the contents and copy (Ctrl+C).
8. From the Edit menu, select Add Value.
9. In the Add Value dialog box, in the Value Name box, type the name of the font that you want to set up font linking for (for example, Arial).
10. In the Data Type box, select REG_MULTI_SZ and press OK.
11. In the MultiString Editor, paste (Ctrl+V) the values you copied for Tahoma or Microsoft San Serif and then click OK.

The next time you restart the computer, the new font will be linked to all the fonts that Tahoma or Microsoft San Serif are linked to.
