The script included in my email doesn't work on Windows 7. It's pretty simple (no environment variables, etc.). It produces an MSI that can be installed but not uninstalled.

Subject: Re: [WiX-users] When are elevated permissions dropped? It's more likely related to something that is no longer correct during the uninstall. Between DeleteServices and InstallFinalize the items that are uninstalled include registry entries, type libraries, environment variables, files, and folders. Deferred and before InstallFinalize basically means that nothing of your product is left behind, so I would look for something your script requires that is no longer there. Permissions don't change in that area of the uninstall.

To illustrate a problem I'm having with a real project, I created a test script that runs a custom action that requires elevated privileges during uninstalls. If I configure it to run before "InstallFinalize" (deferred, no impersonation), the uninstall fails to complete. The event log says "A program run as part of the setup did not finish as expected" and indicates the program being called by the custom action. Changing it to run after "DeleteServices" works. I think that this indicates a problem with permissions. Shouldn't the elevated permissions remain before "InstallFinalize"? Here's the script. The custom actions and the install execute sequence are the interesting parts: <?xml version="1.0" encoding="UTF-8"?> <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi";> <Product Id="*" Name="Foo2" Language="1033" Version="1.0.0.0" Manufacturer="Foo" UpgradeCode="55369FED-96BF-4D95-99E4-E7D746A54C62"> <Package InstallerVersion="200" Compressed="yes" InstallScope="perMachine" /> <MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." /> <MediaTemplate /> <Condition Message="You need to be an administrator to install this product.">Privileged</Condition> <Feature Id="ProductFeature" Title="FooInstaller" Level="1"> <ComponentGroupRef Id="ProductComponents" /> </Feature> <CustomAction Id="AddEndpoint" Execute="deferred" Directory="INSTALLFOLDER" ExeCommand="[SystemFolder]netsh.exe http add urlacl url=http://+:49260/Foo2/ user=\Everyone" Impersonate="no" Return="check" /> <CustomAction Id="DeleteEndpoint" Execute="deferred" Directory="INSTALLFOLDER" ExeCommand="[SystemFolder]netsh.exe http delete urlacl url=http://+:49260/Foo2/"; Impersonate="no" Return="check" /> <InstallExecuteSequence> <!-- Configure http ports --> <Custom Action="AddEndpoint" Before="InstallFinalize"><![CDATA[NOT Installed]]></Custom> <Custom Action="DeleteEndpoint" Before="InstallFinalize"><![CDATA[Installed AND NOT REINSTALL]]></Custom> </InstallExecuteSequence> </Product> <Fragment> <Directory Id="TARGETDIR" Name="SourceDir"> <Directory Id="ProgramFilesFolder"> <Directory Id="INSTALLFOLDER" Name="Foo2" /> </Directory> </Directory> </Fragment> <Fragment> <ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER"> <Component Id="ProductComponent"> <File Id="HelloFile" Name="HelloFile.txt" Source="hello.txt" /> </Component> </ComponentGroup> </Fragment> </Wix> ---------------------------------------------------------------------------- -- Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
