Simple explanation; someone is trying to install an "upgrade version", while there is no previous version of the package installed of the product.

Probably, yes.
But somebody sat there and typed that, thinking "That'll work. That'll explain what the problem is."
And probably went home well pleased with his days work.
Then QA passed it as well...

More like someone wrote a message containing the version, which according to a meeting from Q&A, Management and Marketing was deemed to complex, after which a new and improved text was added.

Starting at C# level zero.
Does that exists, or do I have to start from scratch ?
I have a C# application that I need to understand and extract some of the code, but, AFAIK, everything is so tightly coupled with binding and LINQ stuff that I can't wrapped my head around it.
Dead wood or pixel based ...
Thanks in advanced.

I would try Pluralsight or youtube.

Good luck -- my only advice is divide and conquer. Start with something, perhaps the LINQ, and figure out what it does so you understand how the data is being mapped/reduced/filtered. Work your way out, figuring out what each method/property is doing, until you hit the data binding, which is where you can start tying together how the code-behind is interacting with the UI. Along the way, whenever you see something about C# that you don't understand, look it up, which might involve a quick read of how generics and type inference works, which is the basis of LINQ, and some basics of XAML data binding.
[edit]My reason for starting with the code rather than a tutorial is that you will probably encounter specific stuff in the code that no tutorial will decently cover, so the code is, ironically, your best tutorial.[/edit]

Our Microsoft consultant recommended us "C# 5.0 Unleashed" from Bart De Smet. Although it's not the best IT book I've stumbled upon, it covers most of the C# bases and more.
Also In the "Language Integrated Query Essentials" chapter, you will find something about LINQ.

It is very highly ignorance, that higher rep members are welcome with such a post here and not noticed to read first the top of the page or explaining "Google is your friend" 
Nice sh*t

Google is great for specific questions, but when you're wanting a recommendation based on other people's experiences, Google is not the place to go. A forum like this is.

Yes of course Sir.

Remember you in case a low rep mem ask a Q like this here!

Because I prefer asking real professional/person instead of guestimate what is good on google.

I started on winforms and decided to learn WPF.
Before I did so I read around a bit and what I read was that it's a steep learning curve.
I actually found that this book really helped me - Sams Teach Yourself WPF in 24 Hours (Sams Teach Yourself...in 24 Hours)[^]
...and yes it was a very steep learning curve for me, I was unable to bring very much from my winforms experience to bear on learning about xaml and binding.
I would advise against picking up bits here and there on various forums as there is a certain amount of background you need to know before you can do very much.
The good news is that it's a rewarding challenge and understanding the binding and xaml will be of use in other areas and other frameworks you will encounter.
[edit] LINQ is a bit more straightforward and some decent 101/essentials tutorials online should give you enough to start with, I use LINQ a lot nowadays as it simplifies a lot of nested/ienumerable logic[/edit]

Citation from BBC news ...
"In principle, if someone was able to... hack all the autonomous Teslas, they could say - I mean just as a prank - they could say 'send them all to Rhode Island' - across the United States.
"And that would be the end of Tesla, and there would be a lot of angry people in Rhode Island."
This is really scary ... but is it possible ?
