I agree with Pally. It would be best to use the feature as documented in the chm.
In general when using the ExePackage/@DetectCondition the chm says "Burn uses this condition to determine how to treat this package during a bundle action; for example, if this condition is false or omitted and the bundle is being installed, Burn will install this package. " So it would seem that it is good that your DetectCondition returned false in the scenario which you described. You further indicated "It shows the message "Microsoft .NET framework setup" but then goes on to show the popup as below that shows the various usage options: Setup[switches] " which proves that Burn DID launch the exe, but that the EXE did not like the command line switches which were provided in the InstallCommand. So this is not a Wix issue, but a matter of which command line switches are the correct switches for that EXE. I would open a CMD box on a target system and manually enter the path to the exe and the command line switches to figure out which switches are correct, before trying to integrate the command into Burn. But again in this case Wix makes it very easy to install .Net 4.0 without authoring a ExePackage, so just do as Pally suggested. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Bootstrapper-for-NET-framework-4-0-install-does-not-work-properly-tp7593004p7593050.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Subversion Kills Productivity.
