Project “Project” and “Bootstrapper” for checking and setting preconditions

Question

Here is my situation:

• I am creating a regular WiX installation project.
• Then I try to check some prerequisites, for example, if the .NET platform is installed.
• It seems that I cannot do this from the WiX Setup project. Therefore, I am creating the WiX Bootstrapper Project, and I can verify and establish these premises.
• I am trying to use WiX Bootstrapper in a WiX installation project, but I cannot. In the examples I see, the WiX Bootstrapper project uses an installation project with a tag MsiPackage.

It seems strange to me to start the installation project from the Bootstrapper project. Instead, I prefer to check and install prerequisites from the installation project (maybe call the bootstrapper project from the installation project).

So here are my questions:

• Can I check and install some of the prerequisites of the .NET framework in a Wix Setup project? If so, how?
• Can I launch the application from BootStrapper WiX and call the WiX installation project from it? Is this a general agreement?

Answer 1

• You can check dotnet on wix setup. But you cannot set the preliminary details from the setting. Thus, you can send a message asking you to install dotnet before installation.

dotnet 4.0 wix.
