Any sort of install failure requires manual troubleshooting - best practice is to download manually to the machine and run it. That will produce you an actual error message. Keep in mind BigFix is just meant to automate remotely what you would do on the boxes manually but it will NOT overcome OS-level issues for you…
If you don’t want to do the above then look up the exit codes - specifically for patches, msi installers, etc Microsoft do keep them standardized: link. Per the referenced KB, Exit Code = 1618 seems MS Installer is already running (may be stuck running), with some other install… you need to kill it (if you can, I have seen instances where once you kill it whatever is launching it, just restarts it automatically and get it stuck again) and try again.
