Just to keep a sense of humour here...
Based on that argument,
there has never been a serious issue with Microsoft. 
And no, not using this software in a pro environment. Home only. For fun and relaxation (????)
OK - something bombed during your install - that happens but in the vast majority of cases, it's not down to the app but the environment the app is being installed into (aka MS Doze). The installer is .msi (which stands for MicroSoft Installer). An out of date Windows Installer can screw things up, as can leaving apps running during the install (such as anti-virus). You did read the bit where it said to turn off any running apps before install didn't you?

As for the 'mass of posts' (en masse btw is basically French for everyone going together - check with a Quebecois

), look at it this way. The number of people on this board is a total number of people who have enquired about different things (and not all problems with installation - some are looking advice on different ways to do something) but that includes users of programs back to ECD4 and also Mac software dating back a number of years. There are also sections for Roxio Labs software (nothing to do with EMC0. Now the total number of people who registered is, at the latest count, 43,706, so, bearing in mind what I said earlier, do you honestly believe that Adaptec/Roxio/Sonic have only sold 44,000 copies of ALL the software, going back a lot of years?
I've had problems with installing software myself - and not just Roxio (actually that hasn't given me as much trouble as some other apps) but I keep an image copy of muy hard drive and update that regularly (I use the old PowerQuest DriveImage program but others are using Norton Ghost). If something screws up, I simply re-install from the image and have all my apps back (documents and files are kept on a separate drive so they never get touched).
It's a bit late, unfortunately, to remind you of the first three rules of computing: backup, backup and then backup
