The DetectCondition helps you know whether the package is installed or not. The InstallCondition allows you to choose to install a package even if the DetectCondition is true, or to choose not to install a package if the DetectCondition is False.
I use it because I have to install SqlExpress in a specific case (depending on my UI), the detect condition helps me to know whether it is already installed, and the install condition has to be true (my specific case) to allow the installation of SQLExpress. Does it make sense ?

Objet : Re: [WiX-users] Burn - what's the difference between InstallConditionand DetectCondition? I've not looked at Burn but I would guess you could install something under a wider variety of conditions that it just being already present or not. For instance you might want to install a package based on OS or language or on the presence of other products. -----Original Message----- From: Aled Hughes [mailto:trestlemon...@gmail.com] Sent: 08 November 2011 15:22 To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] Burn - what's the difference between InstallConditionand DetectCondition? With burn, what is the difference between the DetectCondition and InstallCondition on the <ExePackage> element? I noticed that the NetFx4.wxs file in the WiX sources uses DetectCondition to seemingly prevent installation of .Net4 if it is already installed - but isn't InstallCondition the same? ----------------------------------------------------------------------------- - RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users SDL PLC confidential, all rights reserved.
