I have one problem with using hijack's patch on my 5 CD version.
All of mygame files are ok.
My hl2.exe files (in main directory and in SteamApps\myusername\half-life 2) has now 84 kB (originally 1.91 MB).
I've install hijack both patche's first 1.0, later - 1.5 (in main dir, where I have stream installed) and I have the same problem.
So, when I'm trying to run Half-Life 2 from Steam menu (after run hijack_hl2.exe of course and correct logging to the steam) I have message box:
SteamStartup() failed: SteamStartup(0xf,0x12e648) failed with error 108: The local Steam Service is not running
I was trying many things, but I haven't now no ideas
I have WinXpPro, if it could help you.
Thanks in advance.
