The problem with x86 (32-bit) is that there's two different memory limits. 
The total amoumt of accessible memory is 4GB (2^32 Bytes) but the total 
amount of memory per process is limited to 2GB. That means that even on 64-
bit system and more than 4GB of total memory a 32-bit process cannot 
access more than that, which is why a ZIP file larger than that can cause 
trouble on any system. I highly doubt that Windows will be able to 
decompress that file. Depending on the tool you use (built-in unzip tool? 
Winzip? Winrar? 7-zip?) you might be able to access the file and view its 
contents, but you will probably fail unzipping it.
