MSIs are so bloated and horribly designed, it isn't even funny. Why does it insist on storing a copy of the entire .msi - and any patches - in C:\Windows\Installer? From what I've observed, the original MSI is required to perform repairs and reconfiguration, or setting up new-user defaults for that app. This seems horribly inefficient to me, and on heavily used system this can easily waste space on the C: drive.

And occasionally you run into issues with the MSI database corrupting, where you can't install/upgrade/uninstall something (we see this commonly with Adobe apps) , so you'd need to resort to third-party tools like MSI Zapper to get rid of all the references from the database. What a messy system.

I miss the days when programs used to use NSIS (Nullsoft) installers - they were tiny, and super easy to make and automate.

To make an uninstall of course you need the msi db parts (but you wouldn’t need the entire binary content). To make a reinstall (aka repair) you DO need both the db and the content.

I haven’t heard msis being bloated. I assume they contain exactly what they need to contain (though unsure about compression methods).

In the past when storage was scarce it seems like a strange design but these days I can’t say it feels so wrong.
