CLSIDFromProgID failed as admin user.
But it's working as normal user.
Why?

Maybe it is related to Application Compatibility: UAC: COM Per-User Configuration)

After reading this thread, I still don't know what to do.
The given progid is now Excel.Application.16.
So how should I configure it in the registry?
Could you help me please?

It would be unusual for a Microsoft Office application like Excel to be registered per-user instead of per-machine.

Have you tried with the ProgId Excel.Application?

You can also use the registry editor to look for the ProgId in HKLM\Software\Classes which is where a per-machine registration would be written.

tried with the ProgId Excel.Application but it's still not working.
I searched the registry and only found it in here:

Do you use UAC? Whether RUNASINVOKER is set？

The UAC is enable. And I expect to run the exe as an administrator(High Privileges).

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

Add the exe file path of the application, modify the parameters, and set the data value RUNASADMIN

As @Castorix31 's thread say, CLSIDFromProgID() is not working as administrator. It mentioned the need to configure COM objects for the registry. But I don't know how to do.

I have used CLSIDFromProgID as the administrator, and there is no problem. Could you please provide your code, which does not contain any personal privacy

The code is from a jni-dll project.
A github link of the code(at line-num 133) : https://github.com/freemansoft/jacob-project/blob/main/jni/Dispatch.cpp

Main code:

Look at this simple code:

Runing in the normal terminal:

Runing in the admin terminal(selected Run as Administrator):

Obviously,it returned non-zero on my computer while running as administrator.

Confusing!!! Haha.

I have tested your code on Windows 10 and 11, x86 and X64 with success using user and administrator.
Here is the code I tested yesterday.

#include <Windows.h>
#include <iostream>
using namespace std;


int main() {

    HRESULT hr = CoInitialize(NULL);

    CLSID clsid;
    hr = CLSIDFromProgID((LPOLESTR)L"Excel.Application.16", &clsid); 
    cout << "clsid:" << clsid.Data1 << clsid.Data2 << clsid.Data3 <<clsid.Data4 <<endl;

    CoUninitialize();
    system("pause");

    return 0;
}

I have also tested the code on Windows 7. And it's ok. It only return non-zero on my computer. So sad....
So Is there a problem with my registry? Do you know what the problem is?

If you want to run the code as administrator, try registering as an admin and accessing as an admin

You mean reinstalling MicroSoft Office as an admin?

Give it a try, since I can't reproduce your problem on my computer, so this is just a guess based on Windows registry.
