[wix-users] Fwd: Install WiX Bootstrapper Prerequisite Before Displaying UI

[Wesley Manning]

That's a capability in newer Wix versions.  Most tutorials are for older versions.  I think older versions the first item in the chain gets installed before the BA is called (which means only one package can be installed before your managed BA is called).

You don't need a managed BA though, you can create a C++ BA. Then there's not the above complication.  There's not much documentation out there but this is talked a lot in the mailing list.  Even look at github and wixtoolset development section.  Also there is a book you can get that has a section on a managed BA.  Nothing on a C++ BA though so you would have to look at the source code for an example.

Rob Mensching said "It is possible, for example, mba (the managed bootstrapper application host and friends) does this to install NETFX before managed code BA can be loaded."

Can you be a little more specific? I did a search for "managed bootstrapper application" and found the article Custom WiX Managed Bootstrapper Application <http://bryanpjohnston.com/2012/09/28/custom-wix-managed-bootstrapper-application/>.
It shows the installation of .NET as the first item in the Chain element.
It also shows C# and XML code to create the UI. But it does not say anything about .NET being installed before the UI is displayed. In fact the article I mentioned earlier, How To: Install the .NET Framework Using Burn <http://wixtoolset.org/documentation/manual/v3/howtos/redistributables_and_install_checks/install_dotnet.html>,
makes it a point to state that you must target the built in version of .NET.
