Hi Don, The main feature of WI 4.5 that I found to be the most useful was Transactions, but this is only really an issue if you have a multi package installation.
The best option that I am aware of would be to give the customer the chance to take care of the deficiency beforehand. Document it somewhere that the minimum requirement for your program is Windows Installer 4.5, and include a link to the appropriate Microsoft download location. This will allow the user to decide if they want to perhaps schedule the installation for a later time after they have installed WI or if they want to do it immediately. I would still install it as a prerequisite since the user has been potentially forewarned. Mit freundlichen Grüßen / Best regards, Christopher Adkins _____________________________ Work Smart - Connect with DocuWare _____________________________ DocuWare AG -----Original Message----- From: Don Walker [mailto:don.wal...@versaterm.com] Sent: Dienstag, 12.

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.
