Heres a few random thoughts that might help. Im assuming that your MSI requires SQL server express to be already on the machine when it installs, in those cases where the SQL express-dependent feature was selected. If this isnt the case, then just conditionally run the sql server installer *after* your MSI. You could either use a small program to test which features of your product were installed using MSI API, or spawn the sql server installer as a separate async process after installfinalize with the appropriate condition.
Otherwise you will need to split your installation process into separate UI and installation steps. 0. Install any runtimes needed for the next step. 1. Youll need to either write or reuse some bootstrapper software that would collect feature selection information from the user. 2. Using the information from step (1), install SDL server express, or not. 3. Run your MSI with Basic UI or less, passing the feature selection information from (1). In answer to your next question "what software can I use to implement step 1 ?", we wrote our own :) so perhaps other people can share their solutions. If your SQL-dependent feature could be moved into its own msi, it would make it easier to handle in a bootstrapper: MSIs are handled better in bootstrappers than features. Features are rarely handled at all. Alternative approaches would be to embed the sql server express installer within an MSI v4.5-style multipackage transaction. I dont know if this would be wise or even possible, depending on the packageing of it and the legal issues. -----Original Message----- From: Boris Klyachko [mailto:bo...@qbf.com.au] Sent: 27 July 2010 14:12 To: wix-users@lists.sourceforge.net Subject: [WiX-users] Feature specific prerequisites Hi there There have been a number of references in this mail list on how to include prerequisites. The recommendation is to handle prerequisites in the product's bootstrapper. However I have a slightly more complicated requirement: A prerequisite (SQL Server Express) is required only if a particular product feature is selected from the Custom Install dialog . What would be a recommended approach in this case as it is not possible to run an external msj from the product's msi and it is too early to install prerequisites from the bootstrapper?
