VB.NET 2008 Delete reg key Access error

Hi,
I have created a 1 button app that must simply delete a key and its sub keys from the registry in the LocalMachine section. But i am getting an access error.
{"Requested registry access is not allowed."}
Security Exception was caught.

Dim x As Microsoft.Win32.RegistryKey
x = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("SOFTWARE\Test1", True)
x.DeleteSubKeyTree("Testing")

The exception is being generated on line 2 of my code. Is there perhaps another way of doing it? (I have admin wrights on my machine Win7) I need to cater for XP,Vista and Win7n machines

thanks

where have you defined the subkeytree "Testing" thatyou are trying to delete?

Hi,
I am getting the error on the following line before i even attempt to delete the sub key
x = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("SOFTWARE\Test1", True)

have you written that key?

Try the following to see what the value of the key is. If it is "0" then the value is not present

Dim uKey As RegistryKey = Registry.LocalMachine.OpenSubKey("SOFTWARE\Test1", True)
                Dim cKey As String = CStr(uKey.GetValue("Testing", "0"))

Open in new window

Have you turned UAC off?
With UAC on Windows 7 even a user with admin rights cannot access the HKLM tree for writing.

Do you have the same problem with a key in HKCU?
