Hi,
I'm new to this package so please excuse my lack of knowledge and please 
keep any explain simple!  I basically have three questions but I will 
describe my situation first...

I need to produce an installer/uninstaller for a new version of a Windows 
legacy application.  This app is in use on hundreds of computers around the 
world on an "at home" basis so I have no ability to interact with the 
computers and everything needs to be automatic and as foolproof as possible 
as all users are non-technical.   Some users of this installer will be new, 
others have an existing (old) version of this app but they cannot uninstall 
it as that would remove certain files they need to retain.  The existing 
version has no guid's but it is simple to detect when and where it is 
installed as it creates a registry key pointing to the exe.  If a version 
already exists then as part of the install I need to do two things (as well 
as install the new files!) - (1) remove an entry in Add/Remove programs, (2) 
remove a Start Menu folder (and it's sub-items).  Both of these I assume 
would require Admin privs.

So, the 3 questions....
1.  How would I do those two things in WiX?

2.  At uninstall time I need to automatically delete a file that the program 
has created in the application folder, OR, I need to be sure the Application 
folder (under Program Files(x86) ) and sub-folders are removed whether or 
not they are empty.  How would I go about this?

3.  Finally, I having trouble locating some complete documentation on WiX, 
especially a detailed description/list of the various tags/attributes that 
are available, what they do, their usage, etc.  Can someone please point me 
where to start my learning process.

Many thanks
Ian
