UnauthorizedAccessException writing HKCU key values

[RickH]

System.UnauthorizedAccessException
Cannot write to the registry key.
Is what I get trying to write a value in a HKCU\Software key.
My InfoPath form is fully trusted.
I have full permissions on the key according to Regedit permissions
Using vb.net 2003
For that matter, a Windows form I created doesn't allow me to delete a key,
and I can't write a key value in my Outlook com add-in, either.
Account has admin priviledges.
I guess I have been only reading keys, not writing them since vb6.
I've got to be missing something obviuos.

Hi,

This works changing OpenSubKey("Software\Ken", True) to
OpenSubKey("Software\Ken") will cause and UnAuthorizedAccessException.
Dim myReg As RegistryKey = Registry.CurrentUser
Dim MyRegKey As RegistryKey
Dim MyVal As String

MyRegKey = myReg.OpenSubKey("Software\Ken", True)
MyRegKey.SetValue("MyData", "test entry")
MyVal = MyRegKey.GetValue("MyData")
Trace.WriteLine(MyVal)

MyRegKey.Close()

That is the same code that I am using that gives me the unauthorized error.
WHy would my code be failing?
