+#
+# This variable allows specification of a custom root folder ID.
+# The generator specific ``<64>`` token can be used for
+# folder IDs that come in 32-bit and 64-bit variants.
+# In 32-bit builds the token will expand empty while in 64-bit builds
+# it will expand to ``64``.
+#
+# When unset generated installers will default installing to
+# ``ProgramFiles<64>Folder``.
