Thanks. But I want the decision of whether to install SQLExpress to be in my primary msi.The GUI where user specifies his/her preference, and the default selection, is also there.
For now, I believe my best option is to nest the SQLExpress install in my InstallUISequence. An alternative for the future is to write an executble "msiChain": 1. InstallExecuteSequence launches msiChain asynchronously with formatted command line arguments (or environment settings). 2. msiChain waith for the msi session to complete (somehow - not yet decided how) 3. MsiChain launches one or more new installations sequentially. E.g. the SQLExpress installation. Rune C You can't in the Execute sequence, but technically it's possible in the UI sequence as RuneC already found out - but it's a trick and you shouldn't use it for a couple of reasons: If your setup runs in silent or Basic UI mode the UI sequence is skipped and the SQL install won't be called. On Vista your custom action in the UI sequence may not have the required permissions to install SQL because of UAC. In general the UI sequence shouldn't modify the target system and there's no rollback functionality in the UI sequence. A bootstrapper is the officially recommended method to chain two msi setups. -- Stefan Krueger Microsoft Windows Installer MVP Please post your questions in the newsgroup or vist one of these web sites: Windows Installer FAQ http://www.msifaq.com - http://www.msifaq.de InstallSite - Resources for Setup Developers http://www.installsite.org http://www.installsite.de (GERMAN) "Mike Dimmick" <[EMAIL PROTECTED]> schrieb im Newsbeitrag news:[EMAIL PROTECTED] > SQL Server Express uses an MSI installer internally.
