How to install the 1.0006 patch onto a US Steam version:
NOTE: On Vista I ran this all as Administrator. You might want to as well (it may not work otherwise)
1. Run STALKER:SOC at least once to generate the required registry keys and get your CD key
2. Download the US 1.0005 to 1.0006 patch; it has the filename stk-npr-efis-patch-5-6.exe
3. Run regedit and browse to:
32 bit OS: HKEY_LOCAL_MACHINE\SOFTWARE\GSC Game World\STALKER-SHOC
64 bit OS: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\GSC Game World\STALKER-SHOC
4. Modify the InstallVers key to read "1.0005" instead of "1.000500"
5. Create a new registry String (right click->New->String Value) named InstallLang
6. Double click the new InstallLang and enter en into the Value Data field.
7. Close regedit
8. Go to http://www.quickpar.org.uk/ and download and install QuickPar 0.9.1. This is the patcher that will transform your Steam exe into a retail 1.0005 exe
9. Go to http://rapidshare.com/files/304239873/XR_3DA.exe.SteamtoRetail.1.0005.PAR2 to download the patch file. Put this file into your \steamapps\common\stalker shadow of chernobyl\bin folder.
10. Open the .PAR2 file with QuickPar and click the Repair button. You now have a retail 1.0005 exe!
11. Run the 1.0005 to 1.0006 patch.
12. We are not done yet! Some of the files (notably the BattlEye files) have been installed into Program Files. Browse to Program Files (or Program Files (x86) on 64 bit OSes) THQ\S.T.A.L.K.E.R. - Shadow of Chernobyl and select all files and copy them to your \steamapps\common\stalker shadow of chernobyl folder, saying yes to overwriting folders.
13. Finally run the game through Steam and play multiplayer games!
