I'd bet you haven't changed this variable. Id="$(var.ProductCode)"
While in there make sure this is set to what you want also. Version="$(var.VersionNumber)" Make sure you do keep this one the same (it is if you get the message you mentioned) UpgradeCode="$(var.UpgradeCode)" -----Original Message----- From: Tim Hawes [mailto:haw...@anx.com] Sent: Thursday, March 28, 2013 7:25 AM To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] Cannot create major upgrade installer I have been wracking my brain on this for a day and a half. I am trying to make an installer that will uninstall the older version of the software and install the new. The old version is in the registry as 2.1 and the new one I am trying to install is 2.2.1 For the life of me, I cannot create an msi file that uninstalls the old version and installs the new. I have worked through the tutorial linked from wixtoolset.org, and have googled around the net looking for a solution to this. It keeps coming back and telling me: "Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel." (I am using a Windows 2003 server instance as my development environment). I have a wxs file that begins with: <Product Name="SomeProduct Scanner $(var.VersionNo) Build $(var.BuildVersion)" Id="$(var.ProductCode)" UpgradeCode="$(var.UpgradeCode)" Language="1033" Codepage="1252" Version="$(var.VersionNumber)" Manufacturer="Some Business"> <Package Id="*" Keywords="Installer" Description="SomeProduct $(var.VersionNumber) Build $(var.BuildVersion) Installer" Comments="SomeProduct is a registered trademark of Some Business" Manufacturer="Some Business" InstallerVersion="100" Languages="1033" Compressed="yes" SummaryCodepage="1252" /> <Media Id="1" Cabinet="SomeProduct.cab" EmbedCab="yes" /> <Upgrade Id="$(var.UpgradeCode)"> <UpgradeVersion Property="OLD_VERSION_FOUND" Minimum="0.0.0" IncludeMinimum="yes" Maximum="$(var.VersionNumber)" IncludeMaximum="no" OnlyDetect="no" IgnoreRemoveFailure="yes" MigrateFeatures="yes" Language="1033" /> </Upgrade> <InstallExecuteSequence> <RemoveExistingProducts After="InstallInitialize" /> </InstallExecuteSequence> -- Tim Hawes Programmer haw...@anx.com Direct: 919-695-4282 Cell: 919-656-2135 ------------------------------------------------------------------------------ Own the Future-Intel® Level Up Game Demo Contest 2013 Rise to greatness in Intel's independent game demo contest.
