Installing FONT on VISTA from my program fails

[Patrice Terrier]

On VISTA, i would like to install a new font from my program.

But wathever i am doing, i always get an "access denied" error...
(administrator privileges)

I have used both AddFontResource and AddFontResourceEx, with no luck.

I did several search on Google, showing me that this is a common VISTA's issue, however no solution found yet.

Do you have one?

Hi Patrice,

Have you created a manifest file with the following section in it?

    <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
        <security>
            <requestedPrivileges>
                <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
            </requestedPrivileges>
        </security>
    </trustInfo>

If the program has "admin" access in general then it can do things like install fonts, write in restricted folders etc.

You can also directly embed the manifest into the rc file this way.

#include "resource.h"
#define IDR_MANIFEST 1 // 2 for a DLL
#define RT_MANIFEST 24
 
// Other rc entries here......
 
 
 
// Manifest data.
IDR_MANIFEST RT_MANIFEST MOVEABLE PURE
{
    "<assembly xmlns=""urn:schemas-microsoft-com:asm.v1"" manifestVersion=""1.0"">
       <assemblyIdentity
         name=""Microsoft.Windows.Shell.shell32""
         processorArchitecture=""x86""
         version=""1.50.00.01""
         type=""win32""/>
       <description>Windows Shell</description>
       <dependency>
         <dependentAssembly>
           <assemblyIdentity

             version=""6.0.0.0""
             processorArchitecture=""x86""

             language=""*""
           />
         </dependentAssembly>
       </dependency>
       <asmv3:trustInfo xmlns:asmv3=""urn:schemas-microsoft-com:asm.v3"">
         <asmv3:security>
           <asmv3:requestedPrivileges>
             <asmv3:requestedExecutionLevel
               level=""asInvoker""
               uiAccess=""false"" />
           </asmv3:requestedPrivileges>
         </asmv3:security>
       </asmv3:trustInfo>
     </assembly>"
}

Scott,

I want to do it in "silent" mode!

Using "elevated privilege" when UAC is enabled, pops up the infamous UAC notification each time the user starts the program.

Moreover it doesn't install the font! (i am using VISTA 64-bit)


PS: I don't want to reboot the system either.
