See attached screenshots. You only have to set it to an existing (writable)
folder before the replace actions take place.
In this case, our temporary file folder is set to %_SB_INSTALLDIR% which
points to c:\reboot. The sbuilder.chm file is in-use and locked. The
installer writes the "new" sbuilder.chm to c:\reboot\~SB419B.tmp. After the
reboot, Windows deletes the "old" sbuilder.chm and renames ~SB419B.tmp to
sbuilder.chm.
