Thanx Tomcat76 for your support. I've just finished a few test with the final 1.7.4 version and discovered that the problem with roots update is gone. Also I don't know, what exactly Windows Update requiered in my previous installs, because in the last test there was no need of updating compenents. Well, sorry for bothering, seems like everything is OK now. Hypotheticly is there a possibility, that something is not processed as expected on a slower PC (like Thinkcentre E50 9216)? Guess I forget, that MUIs aren't supported by HFSLIP. And about MSN/Live Messenger I was just curious and little bit confused (mostly by MSNMSGS.MS_ file), but I found out, that file MMSSETUP.CAB is important in "installing" MSN/Live Messenger, so putting Install_Messenger.exe in HF folder is just useless, but perfectly processed by HFSLIP
