If you receive:
An error occurs while the spelling is being checked
when spell checking in OE5, or you receive:
The spell check on this document was halted. Do you want to send anyway?
when sending a message (check spelling before sending message is configured), the spell checker, Csapi3t1.dll, was not found.
It should be in the C:\Program Files\Common Files\Microsoft Shared\Proof folder.
If it is there, then your registry entry is wrong. Use regedt32 to navigate to:
HKEY_LOCAL_MACHINE\Software\Microsoft\Shared Tools
Double-click the SharedFilesDir value name, a type REG_SZ entry, and set
the string data to "C:\Program Files\Common Files\Microsoft Shared\"
The path is one level up from the Proof folder, must end it a backslash, and must be encapsulated in " marks.
