Just on the off-chance.. did you rename any of your msi files ? You get that error if you do.
-----Original Message----- From: Joe Tilley [mailto:[email protected]] Sent: 03 August 2011 21:04 To: [email protected] Subject: [WiX-users] How to handle conditional features on upgrade I have an installer that uses property values passed on the command line to determine which features should be installed. Example: <Feature Id="HardwareDefinitions.Internal" Level="1"> <ComponentGroupRef Id="GRP_InternalHardware"/> <Condition Level="0"> <![CDATA[Installed OR ALLHARDWARE = 0 AND INTERNALHARDWARE = 0]]> </Condition> </Feature> The problem I'm having is during upgrade when the new MSI is trying to remove the previous installation. If I'm going from a full install (all features) to a lesser subset of features, I always get a "network error" saying that it can't read the old MSI ("A network error occurred while attempting to read from the file"). This error doesn't occur when I go from a subset of features to a full install. I'm guessing this has something to do with the new MSI trying to uninstall features that haven't been marked for installation in the new install? I'm always doing a "major upgrade" (package ID, product ID, & version # change, but upgrade code remains the same). Any ideas on what would cause the "network error"? I've tried messing with RemoveFeatures and MigrateFeatures in my UpgradeVersion element, to no avail. Here is where I'm doing the upgrade check and remove existing features operation: <Upgrade Id="$(var.UpgradeCode)"> <UpgradeVersion Property="OLD_VERSION_FOUND" Maximum="$(var.ProductVersion)" IncludeMaximum="no" OnlyDetect="no" IgnoreRemoveFailure="yes" /> <UpgradeVersion Property="NEWER_VERSION_FOUND" Minimum="$(var.ProductVersion)" IncludeMinimum="no" OnlyDetect="yes" /> </Upgrade> <!--Put the upgrade check in the InstallExecute Sequence--> <InstallExecuteSequence> <RemoveExistingProducts After="InstallFinalize" /> </InstallExecuteSequence> Thanks _____________________________________ Joe Tilley FW Murphy Software Engineer Office (918) 317-4130 Email [email protected] “This message and any attachments may contain FW Murphy information that is highly confidential, privileged, and exempt from disclosure.
