Re: MSI compression

 

ROFL!

"Fixed"? 

MSI files are actually Windows Structured Storage files (http://msdn.microsoft.com/en-us/library/aa380369%28v=VS.85%29.aspx).

In order that older tools and OSes can read them, they really can't change the fundamentals of how the files are written and store data. I can't see them ever adding a compression layer on top of structured storage (they'll tell ya to compress it yourself before storing it).

Luckily, our MSIs won't have near as much stored in the uncompressed area as we don’t use a lot of the crap in Windows Installer, therefore CoApp MSIs shouldn't heavily suffer from this problem.

When will this be fixed?
