Now consider a console application called install. It's neither a GUI application, nor is it an installer application in the Windows sense. It's just called install.
In my case it's part of GNU coreutils and it's called install because it's usual task is to install software on the system. However, it's perfectly valid to call install as normal user and use it to install stuff into a subdirectory on which you have permissions.

Corinna, it seems to me that porting cygwin tools has become harder as of Windows Vista. Good luck, Juergen. That will result in getting an elevation prompt for your install. That is probably what you want anyway for a program that installs stuff - and thus probably needs to have elevated permissions.
Thursday, December 14, AM. I'm going to reply to all postings in this thread in one go for clarity. I can't understand how a serious design can handle executables differently, just because they happen to have some arbitrary substrings in their name. Using this sort of "heuristic" is bound to result in trouble.
Substrings like "instal", "setup" or "update" are in no way sure signs of an application installing something on the system which requires special privileges.
A modified exe should still work correctly on prior Windows operating systems. The application manifests have received an upgrade in Windows Vista. The Windows application manifest has been enhanced with attributes that allow developers to mark their applications with a requested execution level. These new attributes indicate to the system that you have a legitimate administrative application. The system will automatically ask for approval from the user to launch the application with full privileges.
Microsoft has implemented an extension to the trustInfo section of the Windows XP application manifest schema. The following is the format for this:. If only a small number of features in an application will require administrative privileges for example, an application needs to configure a firewall , the main process of the application must still be run as a standard user.
When we create an application in Visual Studio a default manifest file is created. Can I change this manifest file to include "requestedExecutionLevel" tag, so that my application always runs with admin privileges? Is there any other method through which my application runs with admin privileges without asking user admin or standard to run my application as "run as admin"??
Set this to requireAdminstrator. This will cause the default generated manifest to include the requestedExecutionlevel that you need, so that your users will be prompted automatically to elevate their privileges if they are not already elevated. Lipika The person whom asked the question revealing that admin access was the reason why access to system directories were redirected to virtual directories.
It was later clear that lack of admin access cause writing to certain registry keys to fail. Nayana's link to polynomial's answer is also good. Here I will borrow part of his answer in my demonstration. As Lipika have stated, you require admin access, else Windows Vista and up will redirect you to a virtual directory. Which is great. Logically then your app should request admin access. You can let the user do it manually.
If not, Windows provides many ways to do this programatically. The easiest way is to declare it in your app's manifest.
Here I will dedicate instructions to individuals not using Visual Studio. With CodeBlocks its very import that this file has the. Copy the following code into this file, and add it to your project. Create a manifest file called adminAccess. In Wrapper mainfest column add this file manifest file. Then click "save configuration" option and then click-- Build Wrapper.
