Unhandled Exception when trying to add registry key

问题

When I use the following code My.Computer.Registry.LocalMachine.OpenSubKey("SOFTWARE\Microsoft\Windows\CurrentVersion\Run", True).SetValue(Application.ProductName, Application.ExecutablePath)

to add a registry key to make my program startup automatically, it works on my system but on everyone who I have sent it to gets an "Unhandled Exception" message saying that access is denied. I was wondering if there is a solution to this. Thanks

回答1:

You get "Access denied" because you are required to run your app with administrative privileges if you want to write to the HKEY_LOCAL_MACHINE key.

You can force your app to only run with, and therefore always ask for, admin privileges by doing the following steps:

1. Right-click your project in Visual Studio's Solution Explorer window and press Properties.

2. Make sure you are on the Application tab, then press the button that says View Windows Settings.

3. In the app.manifest file that opens in the editor locate the following:

   <requestedExecutionLevel level="asInvoker" uiAccess="false" />
   

   and replace it with:

   <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
