I'm trying to allow my program to write to the HKLM Keys. In order to achieve that I tried to create a manifest file:
<?xml version="1.0" encoding="utf-8"?>
<assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1">
<assemblyIdentity version="1.0.0.0" name="MyApplication.app"/>
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
<security>
<requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
</requestedPrivileges>
</security>
</trustInfo>
<compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1">
<application>
</application>
</compatibility>
</assembly>
But even with this file I'm still getting an exception:
"System.UnauthorizedAccessException" in mscorlib.dll
Cannot write to the registry key.
I'm using VS2015. I click create new element then pick Manifest file. Set the name to MyProgram.exe.manifest. Then in Project properties I select the proper manifest. And finally I'm changing execution level in Manifest file to requireAdministrator and rebuild the program.
But when I'm executing the MyProgram.exe it never shows that UAC window and when I try to write to HKLM in throws an exception. So I suspect the manifest is not working properly.
Please advise.
Thank you!!
You can do like this:
using administrator run program.
No permission to set permissions.

we have a WPF application that currently uses the default manifest setting: "Embed manifest with default settings" and it works for us. We now need to add a custom manifest in order to use a third-party library that requires a setting in there. But we don't want to risk there being any other differences from before. And that brings the question. Is there a way to know what that default manifest that we are using now actually looks like so we can add to it? I have checked the obj and bin folders but didn't find anything in there and internet search hasn't really brought up much.
Thanks
The default manifest that is embedded into the assembly when you build the app looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity version="1.0.0.0" name="YourAppName.app"/>
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
<security>
<requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
<requestedExecutionLevel level="asInvoker" uiAccess="false"/>
</requestedPrivileges>
</security>
</trustInfo>
</assembly>
You can extract it using a decompiler.

How to run a program automatically as admin on Windows 7 at startup?
(9 answers)
Closed 7 years ago.
I have copied the shortcut of my application in startup folder for all users. I want my application to start with admin privileges when the the system is restarted and a non-admin user logs in. This is important because my application is working with the windows services. For stooping/starting a windows service admin privileges are required.
Please let me know how can i do it.
You cannot force it to start with Admin priviliges -That's up to the user who runs your application.
However you can make sure that the application runs only in admin mode by adding this to your Manifest file:
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
Notice that it would pop up a UAC prompt on every start-up.
Goodluck.
Add the following code to your Manifest:
<?xml version="1.0" encoding="utf-8" ?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<assemblyIdentity version="1.0.0.0" name="MyApplication" />
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
<security>
<requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
</requestedPrivileges>
</security>
</trustInfo>
</asmv1:assembly>
I have my own application server which is windows service who communicates with the sql server, in some cases sql server service is stop so I am stating that via this code
ServiceController sc = new ServiceController("MSSQL$SQLEXPRESS");
sc.Start();
sc.WaitForStatus(ServiceControllerStatus.Running);
but it requires administrator privileges to start service how can I start my window service as administrator
Lets split everything into steps
Add file "Application Manifest File" to you root catalog
Select project properties
In application tab Recources group find Manifest field
Paste you new manifest file name. Probably "app.manifest"
Fill file with this info
All information could be a little bit different based on you situation.

i just add this tag in my app.manifest file

it works ...
I have a wpf application which reads from .xaml files to dynamically create views. However, when installed on a non-dev machine, the program says that the program has unauthorized access to the path where the files are stored. We are using relative pathing to read the files. Any suggestions?
Only way you'll have granted access to that Program Files folder is Creating and Embedding an Application Manifest (UAC).
As an example:
Executable: IsUserAdmin.exe
Manifest:IsUserAdmin.exe.manifest
Sample application manifest file:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<assemblyIdentity version="1.0.0.0"
processorArchitecture="X86"
name="IsUserAdmin"
type="win32"/>
<description>Description of your application</description>
<!-- Identify the application security requirements. -->
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
<security>
<requestedPrivileges>
<requestedExecutionLevel
level="requireAdministrator"
uiAccess="false"/>
</requestedPrivileges>
</security>
</trustInfo>
</assembly>
But you definitively must go and read the API.
I'm having some trouble with my C# app that uses win32_networkingadapterconfig. The problem is that I can't use the altering functions in win32_networkingadapterconfig when I use the app on a user that dont have admin rights. I have tried to "run as administrator", but no luck. And I have tried to make a manifestfile with this content in the trustInfo part:
<security>
<applicationRequestMinimum>
<PermissionSet class="System.Security.PermissionSet" version="1" Unrestricted="true" ID="Custom" SameSite="site" />
<defaultAssemblyRequest permissionSetReference="Custom" />
</applicationRequestMinimum>
<requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
</requestedPrivileges>
</security>
Enable clickone security settings are set to full trust. What am I doing wrong ?
There's a "trustinfo" dangling in your snippet. Make it look like this:
<?xml version="1.0" encoding="utf-8"?>
<asmv1:assembly manifestVersion="1.0" xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<assemblyIdentity version="1.0.0.0" name="MyApplication.app"/>
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
<security>
<requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
</requestedPrivileges>
</security>
</trustInfo>
</asmv1:assembly>
There are a number of possible issues which I have listed in the order I suspect is most likely to less likely.
Possible Problem 1
What are your UAC settings? As detailed in Create and Embed an Application Manifest (UAC)
if you have UAC disabled and you request administrator permissions the
Application might launch but will fail later
Possible Problem 2
There could be something wrong else where in the manifest as the assembly information is required. Posting your whole manifest would help.
Possible Problem 3
You have added the applicationRequestMinimum node which is not required for UAC escalation. It may be worth dropping that and trying again.
