It is our practice to require at Windows Installer 4.5 on XP and Windows Server 2003. It has a pretty widespread impact on the client-facing stuff--many of our clients still use XP. Sales applies pressure to not require SP's, let alone Windows Installer 4.5, but the security implications alone are not pretty.

I'm likely to be supporting installs on Windows XP until past the MS end of support date. Most of our customers running XP most likely have Windows Installer 3.1 installed. As far as I can tell, upgrading to Windows Installer 4.5 will force a reboot. Should I require Windows 4.5 anyway? I have two concerns about what will happened if I don't upgrade: 1. I'll use some new property or feature that is not supported by Windows Installer 3.1. I discovered after the fact that I had done this when I made use of MsiLogFileLocation and MsiLogging in a custom action before noticing that they weren't supported. The features supported seem to be well-documented at http://msdn.microsoft.com/en-us/library/aa816408%28v=vs.85%29 so as long as I am careful shouldn't be a big issue. 2. I am more concerned that I will end up using some new property or feature that is not supported by Windows Installer 3.1 indirectly through the use of a WiX feature. Some of the WiX features are quite clearly linked to one or more Windows Installer features and can be checked. I'm not really clear if there are a significant number of undocumented dependencies on Windows Installer versions. Upgrading to Windows Installer 4.5 for XP (and Vista) looks like the safest approach. Comments/opinions would be appreciated. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
