Installer/uninstaller issue

[ahmd]

I have a custom installer that places a program's shortcut on a desktop using the following code sequence:

SHGetSpecialFolderLocation(hWnd, CSIDL_DESKTOPDIRECTORY, &pidl);
SHGetPathFromIDList(pidl, path);

CString pPathLinkTo;
pPathLinkTo = path + LinkName;

//Use 'path' to create a shortcut
IShellLink* psl;
CoCreateInstance(CLSID_ShellLink, NULL, CLSCTX_INPROC_SERVER, IID_IShellLink,
    reinterpret_cast<void**>(&psl));
psl->SetPath(pPathLinkTo);

IPersistFile* ppf;
psl->QueryInterface(IID_IPersistFile, reinterpret_cast<void**>(&ppf));
ppf->Save(pSaveLinkTo, TRUE);

ppf->Release(); 
psl->Release();

I should also say that the installer is running elevated.

Now, when the uninstaller runs (also elevated) it attempts to delete the shortcut created above using the following code:

SHGetSpecialFolderLocation(hWnd, CSIDL_DESKTOPDIRECTORY, &pidl);
SHGetPathFromIDList(pidl, path);

CString pPathLinkTo;
pPathLinkTo = path + LinkName;

DeleteFile(pPathLinkTo);

It succeeds and removes the link from the Admin account's desktop, but what it fails to do is to remove the same shortcut from [another] standard user's desktop on the same system. For some reason the installer creates a copy of the shortcut for the standard user as well.

How do I make uninstaller remove the shortcut from a standard user's desktop too?
