7-zip question

[jasirw]

Hi there,

Recently i've been using 7-zip to compress my programs for silent installation based on all the topics posted on MSFN. its worked perfectly for a number of programs including office 2003. however, when i try to compress Encarta 2006 everything seems to run fine, but during the actual extraction before installation somehow not all files are extracted (i can see a number of important files missing in the temp folder, including setup.exe). my question are a) does this method have a file limit and B) is there anything i need to be changing from install to install (i've been using the same 7zS file for all)

i really appreciate the help
