I would suggest this presumes that the person doing the install knows
what they are doing! In a corporate environment that may be true and in
that case you could build installs with vital off (having said that most
of our installs are run silently so failing is a better option). I think
the install failing is preferable to having a support call because one
"vital" file is missing.

There is a recent PSDK.MSI thread where Simon Scott suspects a
FilesInUse pattern bug:

 

http://groups.google.com/group/microsoft.public.platformsdk.msi/browse_t
hread/thread/17f76202ee2b2742/dc061211ad4db61a?lnk=raot

He thinks MSI is having a false positive on a locked file and that
pressing ignore results in a successful instalation.  In this scenario,
making all component files vital by default would actually result in a
blocked installation.

 

It would be difficult to predict in advance of shipping a product which
files might trip this possible bug so IMHO it might be best to leave
vital not set and let the administrator roll the dice when choosing to
hit ignore, retry or cancel.  If you don't, you'll be getting the
support call anyways since the install rolled back.

are many
        occasions when making a file optional would be ok. I would guess
that a
        lot of installs (mine included) don't set this but that clicking
        "ignore" would actually break the install.

        I just posted a request for comments on my blog, to ask about a
change 
        we're considering to simplify WiX authoring. You can see the
post here:
        
        http://www.joyofsetup.com/2008/05/03/rfc-vitality/
        
        The short version is that we're considering marking all files
with the 
        msidbFileAttributesVital bit set by default. That's a behavior
change 
        and we wanted to get feedback before deciding either way. Please
read 
        the whole post and let us know what you think, either via blog
post 
        comments or mail on this list.
