Installing 5.7 to XE

Hi, i want to install my TMS Component Pack (5.7.3) into XE (i know autoinstall feature is started on 5.8) but how can i do that with manual installation?
Thanks right now..

5.7.3 will not compile under XE, changes are required which were done in 5.8. 
The version 5.7.3 as such is not supported for XE. We recommend to v5.8 that was specifically modified and prepared to be compatible with RAD Studio XE.
