Need help with ZBrush trial on Windows 7!!

[system]

I have an old Motion Computing M1400 tablet with Windows 7 installed and I’ve repeatedly tried downloading the ZBrush trial and installing it but it always stops midway through the installation and this window pops up:

[] I've tried just about everything i can think of. I've run the setup as administrator, I've tried troubleshooting the compatibility, and I've gone into the setup properties and messed around trying to see what would work, and nothing does! Can anyone help please!!
