Ok, well not ok.
I tried it with HKEY _CURRENT_USER,... and still the same result.
"Access to the Registry Key .... is denied

(It is my own machine, I have Admin rights....)
3 days wasted...trying to get something supposedly simple right, which took
me all of 5 minutes in Delphi (and I've only had 3 months experience
there..!!)

and then I suppose this will all be revisited upon deploying it to the
Production Server.

Seriously Frustrated

SO... NOW WHERE TO ???

Heres the code..
'//I try and create the subkey "UCT-SPLUS" in HKEY_CURRENT_USER\Software

ie
        Try
            Dim f As New
RegistryPermission(RegistryPermissionAccess.AllAccess, _
                "HKEY_CURRENT_USER\Software")
            f.AddPathList(RegistryPermissionAccess.Write,
"HKEY_CURRENT_USER\Software\UCT-SPLUS")
            f.Assert()

            Dim subkey As RegistryKey =
Registry.CurrentUser.CreateSubKey("Software\UCT-SPLUS\DbPwd")
            subkey.SetValue("DBPwd", sPwdValue)
        Catch ER As Exception
            Throw New Exception("Error writing to Registry : " & ER.Message)
        End Try

TIA
