I'm trying to update from the to the 91_603_000. I have 2 computers, one running Windows 7 and the laptop is running Vista. Both computers are using IE 8 and both updated on windows files.

I download and save the zonealarm update file to my computers' desktops(I've tried this 4 times now), I get the same error that the ZASPsetup 91 603 000 en.exe is not a valid Win32 application. I've never had this problem before updating zonealarm extreme security in the past 2 years I've had it. Technical help wants me to save to another location and run disk clean up which doesn't help. I'm frustrated with them. My next option is to uninstall and reinstall zonealarm, but I thought I would see if someone here had another idea of what's causing this.
