A while back, I I learned about how Windows Installer interacts with UAC on Windows Vista. Included in that blog post is a list of steps that must be taken to create a per-user MSI that will not cause a Windows Vista UAC elevation prompt when installing it.Since then, I've gotten a few questions about exactly how to create an MSI that implements those guidelines. As a result, I decided to create an example MSI to demonstrate these concepts, and also post the setup authoring for this example (created using a recent build of ). Hopefully, this example will help translate the per-user MSI creation guidelines into real-world MSI concepts so that anyone who wants to create their own per-user MSIs will be able to do so relatively easily.For this example, I chose to create a per-user installer for a because this type of application does not require installing any per-machine resources (as long as you do not user the /allusers switch when calling as a custom action during setup to register the application with Media Center). Hi,I have an application that is designed for XP, VISTA and Windows 7.For the earlier version, the installer was used with 'run as an Administrator'.For the new version, we want it to be installed on per user basis. I tried to modify the installer using the package attributes above.I retained just after building the installer.After building and viewing msi file in ORCA I find that ALLUSERS which I did not define to have any value is set to 1 (implying installs will be per machine).I have some questions about this.I am not writing to any common areas (program files, HKLM etc.)I am however, installing a third party driver through custom actions.
I want to use an MSI installer property in a condition message in a WiX installer. This MSI property is set by a C custom action. I can set and get the same MSI property and value before calling the condition message, but it is failing when I use it in condition message. Non-existent property names will be treated as empty strings. The logical value of a property reflects whether it has been set-meaning that you cannot check for a logical value by simply using the property: PROPERTY This will evaluate to true if the property has been set and has any value, even if this value is false or 0.
Hi Umesh – Simply setting ALLUSERS to blank is not enough to make a.msi file a per-user.msi. Driver installations are per-machine, so you won't be able to create a per-user.msi that installs a driver. Also, the VC runtime files are per-machine, so you won't be able to install those in a per-user.msi.To create a per-user.msi, you have to follow all 3 of the rules listed in this blog post – do not install anything to a per-machine location, set ALLUSERS to blank, and set bit 3 of the word count summary property to 8 (as documented at ).Upgrading a per-machine.msi to a per-user.msi will require elevation when it does the RemoveExistingProducts and uninstalls the previous version of the.msi.

I'm writing an installer file in WiX with a custom action defined in a DLL. The custom action runs on uninstall, and if it fails, I want it to stop the uninstall process and rollback. The action doesn't affect the system, so I am able to call it before InstallInitialize, so it shouldn't have other changes to undo.I was told that if I defined a property for the custom action, I could then use condition to halt the uninstallation process, as follows: Installed AND remove=ALLInstalled AND remove=ALLNOT (Installed AND remove=ALL) OR CAmine = 'No'Where mine sets the property CAmine to be 'Yes' if I want the uninstall to stop.Would this even work? When is the condition tag evaluated? Is there a simpler way to accomplish my goal here (rolling back uninstallation when mine fails)?
