Adding an application manifest with requireAdministrator breaks Installshield custom action

Question

@All,

I was successful in adding and running a custom action see ( Be able to pass the installation directory with a custom installshield setup )

This application needs to run with Administrator rights so I added these (add an application manifest to my c# application and set the following execution level '<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />'

When rebuilding the setup and deploying it on the same machine I now get the message that the file cannot be found see the image below

App.manifest

        <requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />
        <requestedExecutionLevel  level="highestAvailable" uiAccess="false" />

            Specifying requestedExecutionLevel node will disable file and registry virtualization.
            If you want to utilize File and Registry Virtualization for backward 
            compatibility then delete the requestedExecutionLevel node.

Any help is greatly appreciated.

任何自定义操作都不会以提升的特权（管理员）运行，这可能是失败的原因。

Assuming your custom action directly launches an .exe file, Windows Installer uses CreateProcess rather than ShellExecute behind the scenes, and this does not elevate during the process launch. So that means you have to use a custom action scheduling that is already elevated.

In the limited edition, only the two scheduling locations "After Register Product" and "After System Changes" are elevated.
