Corrupt cab files

[Guest]

I have a Winbook N4 laptop and 90 percent of the programs I try to install
will quit because of invalid cab files and some of the ones that do install
will stop during installation to tell me that the information in the cab file
doesnt match and may be corrupt, if I choose to ignore it will intall anyway.
I have reinstalled windows, updated all my drivers, ran memory diagnostics,
ran check disk, defragmented, and gotten all the updates I can. It will also
stop installtion of some exe files saying it's corrupt. The only games it
let me install will only play for a minute then crash, Syberia II wont even
get as far as the main menu. What does win xp pro use to open cab files and
self extracting exe files? What can I do to make it recognize these as valid
files? Any suggestions will be greatly appreciated, I tried winbooks support
but they couldn't tell me anything useful.

Perhaps you mean that installs from a CD drive are failing. That would be a
CD drive driver that needs updating.

It's not that, programs installed from the hard drive wont work either. It
took forever for me to get service pack two on this thing because it couldnt
read most of the exe files, every time the message came up that it couldnt
copy the file I would have to choose browse and have it copy from our desktop
computers service pack files. I don't understand that either, why it cant
read the exe files that were downloaded directly to this computer(the laptop)
but can read the same files through the network from our desktop computer.
The CD driver is update however.

New files downloaded onto your system will not run unless you rightclick the
file, Properties, and click the "Unblock" button (e.g. a htm file that runs
activex)

I was talking about win xp service pack 2 which downloads and installs
automatically but couldnt read the files it came with. Also self extracting
exe files which have no unblock button in their properties
