Delphi manifest for UAC elevation in 64-bit

Question

What's incorrect in this manifest to run an app as Admin? It works fine with 32-bit, but used with a 64-bit exec gives an error on startup and shuts down: "The application was unable to start correctly (0xc000007b). Click OK to close the application."

EDIT: question solved and closed, for future reference:

Working manifest for both 32/64 bit, add it through Project Options/Application/Runtime Themes/Custom Manifest->pick .manifest file. Delphi XE2 resource compiler seems to mess up otherwise for some reason.

<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">

                        />
                </dependentAssembly>
        </dependency>

                                       level="requireAdministrator"
                                       uiAccess="false"/>

</assembly>

Your problem is not related to your manifest. You can verify that this is so by creating an empty application and adding your manifest as a custom manifest.

Error code 0xc000007b is what you get when a 64 bit process imports functions from a 32 bit DLL and this is the most plausible explanation for your woes. Use Dependency Walker to find out which imports are being resolved by 32 bit DLLs.
