; If you are bundling the TAP-Windows driver with your app,

; you should try to rename it in such a way that it will
|

; not collide with other instances of TAP-Windows defined

; by other apps. Multiple versions of the TAP-Windows

; driver, each installed by different apps, can coexist

; and uses macro definitions from settings.in.
|

;
|

; (1) Rename all tapXXXX instances in this file to
|

; something different (use at least 5 characters
|

; for this name!)
|
||||
; (2) Change the "!define TAP" definition in openvpn.nsi
|

; to match what you changed tapXXXX to.
|
||||
; (3) Change TARGETNAME in SOURCES to match what you
|

; changed tapXXXX to.
|

; (4) Change TAP_COMPONENT_ID in common.h to match what

; you changed tapXXXX to.
|

; (5) Change SZDEPENDENCIES in service.h to match what

; you changed tapXXXX to.
