If you don't want to always be calculating version numbers, you can also do this:
<UpgradeVersion Minimum="1.0.0" IncludeMinimum="yes" Maximum="same-version-as-in-Product-element" IncludeMaximum="no" Property="OLDERVERSIONBEINGUPGRADED" /> I personally always set Minimum to "0" because that way I never have to worry about what my minimum version number was or about some pre-release build getting left behind. Many people also use this table to implement downgrade protection. -----Original Message----- From: Sohail Somani [mailto:soh...@taggedtype.net] Sent: Wednesday, August 11, 2010 12:44 PM To: wix-users@lists.sourceforge.net Subject: [WiX-users] Silly but simple question about upgrades First, I love WiX. I don't think I can say that enough. Windows Installer is a huge pain and this product makes it bearable and almost fun. Ok, enough sucking up. I am reading the section about upgrades here: http://wix.sourceforge.net/manual-wix3/major_upgrade.htm It appears that the recommendation is to generate the Product Id every time. In addition to this, I am also generating the Package Id every time. In fact, when I want an installation to overwrite the existing installation (by uninstalling and installing on top), I am only leaving the UpgradeCode as static. Specifically, here are the relevant sections of my wxs file: <Product Id="*" UpgradeCode="A-GUID" Name="Product SDK" Language="1033" Version="1.0.1" Manufacturer="Company Inc."> <Package Id="*" Description="Product SDK" Manufacturer="Company Inc." InstallerVersion="200" Compressed="yes" /> <Upgrade Id="SAME-GUID-AS-A-GUID"> <!-- The Maximum version should be one less than the current minor version (or 0 if negative). The Minimum version should be the first in this product series --> <UpgradeVersion Minimum="1.0.0" IncludeMinimum="yes" Maximum="1.0.0" IncludeMaximum="yes" Property="OLDERVERSIONBEINGUPGRADED" /> </Upgrade> <InstallExecuteSequence> <RemoveExistingProducts After="InstallInitialize"/> </InstallExecuteSequence> Does this sound like a silly, dangerous thing to do or am I a genius?
