--- Comment #23 from AJSB ajsb@vfemail.net 2009-11-25 07:33:36 --- I forgot to mention that i was talking aboout Modern Warfare 2 that also gives the error 53....
This might be interesting....i found it in a CDMW2 related page with WINDOWS users also having a lot of problems incluiding the fake imcomplete instalation report: .................. For users having the Steam error “Installation Incomplete” on windows Vista try turning off UAC (user account control found under user accounts in control panel, reboot the pc) then when installed, to launch the game, right click the desktop shortcut and select “Run as Administrator”… this worked for me.
If the error is still there, delete the game content from within steam and install again with UAC disabled.
Another solution is to not use the “auto run” to install but instead go to start/computer, right click on the drive containing the disc, choose Open, locate the setup file and right click choose “Run as Administrator.” … again when launching from the desktop shortcut choose to run as administrator if you have problems.
Good luck all, Its disgraceful that such a lot of problems exist from the off! ..................
Dunno if this might help find a soluction or not....
