Thanks that's good to know. I am very impressed with the wybuild as a updater and patcher.
The problem I have is that I have a .NET application which needs to have a option to install for "all users" the problem is that with all users I need to have a shared SQL CE database. I believe this is outside the scope of Click Once.
Therefore, I am a little confused to which directories I should be using, should to main program be in Program Files and the database in %programdata% (vista\7) or All Users\Application Data (XP)?
PS needs to run on XP -7, unbreakable in terms of DLLs for SQL CE etc and easy to update..
