You do have to be careful with "ORDER BY" in MSI SQL syntax, it really behaves 
more like a "GROUP BY".  For things that have a Sequence column it doesn't 
really matter but if you're hoping to get alphabetical sorting "ORDER BY" in 
MSI is sure to surprise you.  <smile/>

What do you mean?  According to 
http://msdn2.microsoft.com/en-us/library/aa372021.aspx, there is an ORDER BY 
clause in the SELECT statement.  I've used it once or twice, and it appears to 
work.

I always thought that it was silly that MSI SQL didn't have a functioning ORDER 
BY statement and that many tables where order would be useful don't have ORDER 
columns to allow useful traversing of the record sets.

I once wrote a very sweet custom LaunchConditions pattern.  I write about it a 
bit here for anyone interested in extending LaunchConditions to actually be 
useful.

says: "You cannot guarantee the order.."

They suggest to author a CustomAction type 19, in wix that would be a custom 
action with the Error attribute set, but I have never done that.

Subject: [WiX-users] Execution order of launch condiitions
In our product installs we have several launch conditions set, but the order is 
not from the top down. Is there any way in WiX to set the order of execution?

For example, we would like them to check them machine architecture and 
privileged settings before checking for other support packages to be 
preinstalled.

Can WiX set the order or are we at the mercy of Windows installer to do this? 
Seems kind of basic to be able to do this.
