Then they need to plan their schedules more efficiently. Good quality is never more costly than a frowning customer. Quality management has been my profession for more than the last 30 years of my aerospace engineering career that spanned almost 50 years. I’ve written books on quality. I have proven successes in quality regularly exceeding 25% within 6 weeks of starting a quality management improvement project at space systems suppliers. I spent my last 10 years as a QM for EADS Astrium. I know what a good quality system looks like and msfs/asobo would never get my approval.
As for expensive - in many cases it just needs the people to think more efficiently. Just for example - a couple of simple checking routines in the installer could warn the user of conflicts between his system and the msfs requirements. Just a few lines of code could automatically move the community folder if the user forgets. A few more lines could check and delete the contents.xml
Anyway… without any better alternative, I am forced to do a complete uninstall, system cleanup and reinstall.
Talking of alternatives - things are looking up: I have found a software migration program that will fully back up a functioning “game” and when an update goes wrong, I can roll back without risk.
