In your MSI you might want to look at the 'remember property' pattern. I have found these posts helpful: http://www.nichesoftware.co.nz/node/633 http://robmensching.com/blog/posts/2010/5/2/the-wix-toolsets-remember-property-pattern
I use the above pattern for properties which are passed to MSI packages, which may be needed at a later time even. The MSI package may get launched without the bundle, such as via a 'repair' of an advertised feature. In the bundle if the property is implemented as a 'remember property pattern' in the MSI then I define a variable in the bundle like this: (note that the type is a string, to be used with MsiProperty, and Variable/@Persisted='yes' is not used, since the remember property pattern will be used): <Variable Name='MyStringVariable' Value='*' Type='string' bal:Overridable='yes'/> For variables which I do not need to be passeed into a MSI, but are use to control whether a MsiPackage is installed, I define the variable like this (note the numeric type and the persisted attribute): <Variable Name='MyNumericVariable' Value='1' Type='numeric' bal:Overridable='yes' Persisted='yes'/> Whether I am using the WixStdBA or my custom mba, I implement the logic necessary to set either the string variable or the numeric variable in the ba (using a bafunctions.dll) or mba. There are examples of using either a bafunctions.dll (with WixStdBA) or a mba in the wix toolset source. Then in the Bundle/@MsiPackage the MsiPackage/@InstallCondition looks like this: InstallCondition='MyNumericVariable = 1' The MsiPackage/@MsiProperty looks like this" <MsiProperty Name='MY_REMEMBERED_PROPERTY' Value='[MyStringVariable]'/> I have a lot yet to learn, but this the approach that is working for me. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Set-property-on-condition-in-MSI-tp7594095p7594099.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
