I've been trying to determine if process A, that I installed, is already running on the machine. Process A requires admin priviliges, it is installed in C:\ProgramData and it is usually started as a service. There are many processes on the machine, that are named A. To find out, if this is my process, I inspected the path to exe file.
You can do this with process.MainModule.FileName or more elaborate setup that is documented in this question
Unfortunately, you cannot inspect the path of executable started as administrator without having administrator priviliges your self.
Is there another way to determine if the process with the name A is indeed the one you are looking for? What else can be checked beside path to executable? What workaround do you recommend?
UPDATE:
I misinterpreted the observations. If the process is started as a service, it is run as a SYSTEM user. Because of that, you cannot determine the executable path without having the admin priviliges your self.

Basically I'm writing a tool for my job that replaces a broken file copied incorrectly by a software installation with a working version of the file from another computer.
Part of this tool requires me to take ownership of the folder containing the target file (by default this folder is owned by SYSTEM). I am an admin so I can do this through Explorer with no problem, but the tool that I created is unable to take ownership from SYSTEM, but can take ownership without error if the owner is anyone else (another admin for example)
I already have built a manifest which uses requireAdministrator, and this tool is able to take ownership from SYSTEM on my home computer, but not on my work computer.
I believe this is because UAC is disabled via group policy. Is there any way for me to run this program with admin privileges? Thanks for the help.
At the moment I'm setting up a new project on my TeamCity server, which should simply build and execute a C# application.
The application needs access to a network drive for the execution, so the path to the network drive is passed as argument.
The build step works well, but I get a 'System.UnauthorizedAccessException' according to the path of the network drive, after executing it.
The TeamCity account has administrative priviliges and everything works well if I start it manually.
So, I assume my user account or the build agent still does not posses administrative priviliges? Do I have to set more specific settings at my TeamCity server?
Sorry if this post is a repetition, but among others, this post [0] does not worked for me.
Any ideas? Thx a lot in advance!
[0] how to run visual studio or nunit as administrator from teamcity
The solution of my question is the same as in this question:
Trying to get a Windows Service to run an executable on a shared drive
I have a small C# program to modify a xml file which is located under Program Files. The machine is a Windows 7 machine. This small program is launched by a batch file (called A.bat) because I want to pass a parameter to it.
I have a master batch file (called M.bat) which is the start point. The M.bat will start an installer and wait untile the installation finished. Then the M.bat will start A.bat which will launch my small program with a parameter.
Right now I get the following exception:
System.UnauthorizedAccessException: Access to the path 'C:\Program Files\MyTest\Test.config' is denied.
I know it is caused by tighter security in Win7. It works fine under XP.
I cannot use "Run as Administrator" to start M.bat or manually "Run as Administrator" to start A.bat because both will report cannot find the target executable (because the start location is not really the "current" location then).
Is there a way to start an executable as Administrator in batch file? or in C# program I can give myself Administrator right?
or ...
Not in a way that is invisible/hidden from the user... I would suggest finding a way to make it work when run as an administrator. Or you could set the application manifest (see this: http://www.enusbaum.com/blog/2007/08/26/how-to-run-your-c-application-as-administrator-in-windows-vista/) to run your app as admin, that might work as well.
Bottom line, you cannot run with admin privileges unless you run as admin, or unless your user switches off UAC (which is not recommended at all).
You'll need to elevated your privileges through a UAC prompt. Add a manifest to your program as described in this answer.
You should request for admin privileges at program start up. Look at this sample
I have created a windows application setup program, it needs to have a text file in the application folder. The file is also included while creating the setup.
Once the setup successfully completes and my program tries to modify the file based on user input, its simple throwing an exception.
I am using Windows 7 Home Premium OS.
Any suggestion/help will be great to overcome this issue.
This is normal on a Vista or Win7 machine. Or a properly secured XP machine for that matter. The normal install location for programs, like c:\program files\your company\your app, is read only for most users. UAC is a counter-measure to malware messing with programs.
You'll need to store the text file into a writable location, the AppData folder. In the Setup project, right-click "File system on target machine" and select User's Application Data Folder. Find that file back at runtime through Environment.GetFolderPath, passing Environment.SpecialFolder.ApplicationData. Or use "User's Personal Data Folder" if the user should be able to find it back easily through the Documents folder.
What exception is being thrown? It could be a UAC issue.
Similar to: Request Windows Vista UAC elevation if path is protected?
I have a .NET Client Application installed in c:\Program Files (Windows Vista). This application should update itself, but it doesn't because of permission issues. The auto-updater should simply replace a couple of assemblies, but they are all located under c:\Program File and the application throws the following exception:
System.UnauthorizedAccessException:
Access to the path 'C:\Program
Files...' is denied.
I have no control on where the application could be installed and the permission. Is there any workaround for this? Is it possible to request the Administrator rights for a couple of seconds? Is it possible to pop a UAC window? I am pretty sure that there a workaround... Otherwise, how Firefox would be able to update itself?
Thanks in advance for the help and ideas!
Could you use a Click Once deployment method? We use this for an internal application and users have no problems with permissions when we publish a new version. They are prompted to install the update when they launch the app (if a new version exists) and it installs without a hitch.
You can't elevate a process's permissions halfway through, but you can start up another separate process with higher permissions that can do the work for you.
Get your main application to put all the files / installation details into a low-permission temporary location. When you're ready, start up a smaller application whose only job is to copy over those files to the Program Files directory (and maybe restart your main application with the new updates). Mark that application as requiring the needed permission to copy to the Program Files directory or write to the registry (or whatever else is needed).
