This text assumes that widget installation is always an interactive  
process.  It might very well be part of batch processing, in which  
case an interactive, localized error message might simply be the wrong  
thing to do.

I'd suggest to simply say that an invalid zip archive is a reason for  
the user agent to abort all processing, full stop.  (One could add  
some wishy-washy language about appropriate error reporting, or  
something, but I don't see how that adds much value here.)
