It's not so much that the installers in general are a nightmare, but the backstory is that the Saab installer was originally coded in 2013 and at the time was our most advanced installer code to leverage some attempted load balancing on the server, as well as keeping track of file differences and updates. At the time it seemed like a great idea, but in reality it was a terrible idea that I didn't see coming as time progressed. Keeping track of all these variants and the file updates between them, as well as the many gigabytes of data became tedious in the way the installer is coded, and it caused headaches not only for distribution, but also for people like Goran when we would discover some files were not properly updated between variants at update release times.
Over the years new installer formats have been developed because of this. Products like IXEG, the MU-2, and pretty much any other recent release contains the more up-to-date installer routines. The Saab needs some love to move to this system so we can future proof release delays going forward on it. At the moment it's not top priority over a couple of other projects that are first in line, but as soon as those are out of the way the focus will switch to this and bringing it all up to speed. We need to leverage our time spent on projects appropriately to balance business cash flow for all involved. We'll get there, just not yet.
