Hi,
Hope everything is going well.
1,Is the application running as System or the logged in user? We can check as below in SCCM:
Application Package -> Properties -> Deployment Types (Edit) -> User Experience.
If the Installation Behavior is "Install for system if resource is device; otherwise install for user", change it to "Install for System."
2,We can also try to bypass or disable UAC prompt:
a,Bypass UAC prompt:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
ConsentPromptBehaviorUser DWORD
Change the value to 3 to have a try.
0 = Automatically deny elevation requests
1 = Prompt for credentials on the secure desktop
3 = Prompt for credentials (default)
How to Change User Account Control (UAC) prompt Behavior for Standard Users in Windows
b,We can also try to disable UAC via below command line:
%windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f
