Should SetWindowsHookEx work on Windows 7 on Mac Mini (parallels) - delphi

Question

Given an appropriate manifest that sets uiAccess="true", should a win32 program (that works fine on other Windows7 systems) be able to get a valid handle back from SetWindowsHookEx when running on Windows7 (32bit) on Mac Mini using Parallels ?
This is the line of Delphi XE4 code that calls the API
HookHandle := SetWindowsHookEx(WH_JOURNALPLAYBACK, #Playback, hInstance, 0);
I keep getting "access denied" as the system error returned in HookHandle.
I have tried many variations of my manifest syntax and am seriously wondering whether this is just some limitation of the Mac Mini / Parallels environment. The user invoking the program is an Administrator. UAC is enabled. I have tried Run as Administrator; no difference.
My manifest file follows.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity type="win32" name="FFHotKeys" version="1.1.0.0 processorArchitecture="*"/>
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
<security>
<requestedPrivileges>
<requestedExecutionLevel level="asInvoker" uiAccess="true"/>
</requestedPrivileges>
</security>
</trustInfo>
<compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
<application>
<!--The ID below indicates application support for Windows 7 -->
<supportedOS Id="{35138b9a-5d96-4fbd-8e2d-a2440225f93a}"/>
</application>
</compatibility>
</assembly>
I have tried stting the level to each of these
level="asInvoker"
level="requireAdministrator"
level="highestAvailable"
and that did not solve the 'access denied' problem.
Note: I am including my manifest via .rc file containing
1 24 "FFHotKeys.exe.manifest"
rather than by the Custom Manifest feature under Project > Options. I have "Enable Runtime Themes" and a blank custom manifest. I tried it the other way but with slightly different .manifest contents.
Note: when I check the resources with XN_Resource_Editor, there is an "XP Theme Manifest" resource containing exactly the XML expected. There are also 2 VCLSTYLE resources.
Thank you.

Answer 1

The answer is YES, it should and does work on Parallels.
The problem was clarified by using XN_Resource_Editor to examine the compiled EXE. Turns out the only deleting the .RES file prior to Project > Build led to the resources being recompiled, so test results had been confusing. More importantly, Delphi XE4 uses its default manifest when RunTime themes are involved. Therefore the solution was to delete the resource references in the project and instead use Project > Options, Application, Runtime Themes, select the custom manifest and then Project > Build and code-sign the EXE and run it from under c:\Program Files\subdir.
processorArchitecture="*"
was valid in the manifest
<requestedExecutionLevel level="asInvoker" uiAccess="true"/>
was valid in the manifest.
