I encountered the below error while installing SPSS modeler 18.4.  

Hi @Fahad Almusharraf

As the message indicates, this seems to be a problem with the .cab file in your %USERPROFILE%\AppData\Local\Temp path.  This kind of thing often comes up when you have many temporary files  -- specifically orphaned temp files from abandoned installation attempts -- in this path.  The easiest solution I've seen to date is simply to delete everything in this ..\Temp path.  If a File is in use, a warning will come up and you can skip the file.  Files that aren't  in use are fine to delete.

I hope this helps!
