question about Sapi 5.1 control panel

[M-News]

Do I have to manually ensure that the sapi.cpl file is installed in the
system32 directory on WinXp? Will it hurt anything if that file doesn't
exist in that directory?

I have an application that installs the 5.1 engine through msm files
during the install process. Does sapi.cpl and it's manifest
automatically install into system32 as part of the installation of the
merge modules?

Currently I have some code that copies the sapi.cpl from [..common
file]\microsoft shared\speech\sapi.cpl to the system32 directory on XP,
but sometimes it generates an error when trying to copy the sapi.cpl.

If I can get rid of the offending code by not worrying about it, that
would be great, but I am not sure of the consequences.

Thanks,
Miguel
