Thanks, Steve. I get the same behavior, too, with Win7 SP1. However, that was not what I was pointing out. It was that help within the view application could not be found. Maybe there's an environment variable that needs to be set that would fix it . . .
Ah! OK, I also observe the same issue. The link from the Help button (and from F1) in the VIEW screen is not properly linked to tcmd.chm. Cf. V13, where it properly opens v.chm. When I hard linked v.chm from the V13 to the V14 installation directory, everything worked.
Judging by the size of tcmd.chm and v.chm of V13 vs. the size of tcmd.chm of V14 (latest builds) it does not appear that ALL of the contents of V13 v.chm could have fit, esp. when I consider the considerable added documentation for TPIPE and the other enhancements.
