Can't Install Newest CIS on Older Laptop

I’ve tried to install the newest CIS to an older laptop that had CIS on it since 2011. I deleted the older version and tried to download the CIS today and when it gets to approximately 4% a red info box appears saying the download file is corrupted and when I click on the red box another box appears stating it experienced error 4294967295. I also tried to install CIS by downloading the program and installing offline - same thing happened.

The laptop is a Toshiba Satellite A105-S4074, Intel Centrino Duo, Windows 7 Premium Home edition SP1, 32 bit operating system, 2GB RAM.

Any ideas?
