Are you sure?

The TAP and TAPDEV strings are the actual names of previous TAP-Win32 
hardware IDs which we want to delete before installing the new TAP-Win32 

For example in OpenVPN 1.x, the hwid is "TAP".  If we change the NSIS code
to ${TAP}, now it will expand to "tap0801" which is the hwid for 2.0.  So 
we won't be deleting the old instance any longer, which is what this code 
is supposed to be doing.
