Okay, this is my source code. Say, a machine is never installed with .NET 3.5 SP1 and .NET 4.0. So, now I run the setup.exe file. I purposely cancel the .NET 3.5 SP1 and .NET 4.0 installation, but then it still executes to install the client_win32-setup.exe... How do I check the condition if only the first two had successfully installed before the client installation?

But then I added detectcondition, and it never worked as I expected. The DetectCondition="NOT ((DotNetFramework35SP1InstallRegValue=1) AND (DotNetFramework40FullInstallRegValue=1))" is pre-executed and not after the .NET installation.

  <ExePackage Id="ClientInstall" Cache="no" Compressed="no" Vital="yes"
              PerMachine="yes" Name="ClientInstall"
              SourceFile=".\sources\client_win32-setup.exe"
              DetectCondition="NOT ((DotNetFramework35SP1InstallRegValue=1) AND (DotNetFramework40FullInstallRegValue=1))"  />

Is there a way to solve this kind of sequence validation issue?

Answer 1

What you are seeing is the expected behavior. Burn creates a "plan" that defines all the work that should be done and executes it. Once planned, there is forward progress until a vital package causes a failure and then rollback occurs. It sounds like you need one of the ExePackages before the ClientInstall package to be marked Vital="yes", so the install does not continue if it is not installed.
