Vista - Read from Registry on Vista

I'm using this approach to read from registry.
Dim f As New RegistryPermission(RegistryPermissionAccess.AllAccess, _
"HKEY_LOCAL_MACHINE\SOFTWARE\SRS
Enterprises\Coordinator\Settings")
'Vlad 02/12/2007
Dim f2 As New
RegistryPermission(RegistryPermissionAccess.AllAccess, _
"HKEY_CURRENT_USER\Software\Classes\VirtualStore\MACHINE\SOFTWARE\SRS
Enterprises\Coordinator\Settings")

Dim pRegKey As RegistryKey = Registry.LocalMachine
pRegKey.OpenSubKey("SOFTWARE\\SRS
Enterprises\\Coordinator\\Settings")
Dim val As Object = pRegKey.GetValue("CSSLQN")

It works on Windows XP, on Windows Server 2003. It doesn't work on Vista
Business. pRegKey.GetValue("CSSLQN") returns null. The key with value
exists.

What should I add to my code to get the value from a registry?
Thank you

After the registry permission declaration you don't use demand or assert.
So, you declare it but never use it

Dim f As New RegistryPermission(RegistryPermissionAccess.AllAccess,
"HKEY_LOCAL_MACHINE\SOFTWARE\SRS Enterprises\Coordinator\Settings")

f.Demand() ' Personally I use ASSERT because at the end you can use
f.RevertAssert(), but you cannot do that with Demand()

Please try & post back

Thank you
I tried both one by one. I still get null from the key.

I found the sample of the code a couple of years ago. I replaced its values
with my values and it worked right away.
Since that I never had any problem with that code before Vista.
I use it in Windows Service project.
I tested it in Windows Form project. It works on Vista.
So the same code does work in Windows Form project on Vista, in any project
before Vista and doesn't work in Windows Service project on Vista.
What's the difference?

I guess they got more specific in what they would allow and not allow or
what was conventional or not. I don't know, but the error is probably due
to the double slashes.

I tried single slashes before my original post. The same problem.

I have similar code in VS 2005 and it works fine.
