i installed windows 7 x64 ultimate new. i run microsoft update, install all updates and install the microsoft virtual pc update for xp mode (Windows6.1-KB958559-x64). the install of update has no problems.
i installed cis 4.1.150349.920 (only firewall), the install has an error by kernel driver install, error code is 1603.
is microsoft virtual pc update (KB958559-x64) not installed, the cis install have no problems and cis works.
is cis installed, i can not install the update KB958559-x64. pc make restart and the update install have an error (code 8004005).
i can’t install CIS when the update is installed, the install of cis stops by “kernel driver install” with error 1603, no cis is installed, no diagnostic.
Sorry, I missunderstood your first post. Do you mean that you reinstalled the entire operating system and then tried to install CIS and it gives you the error? No other programs are installed or have previously been installed?
Also, are you sure you tried to install the x64 version of CIS? Sorry, just trying to cover the basics.
