Uninstalling Transcend from NV 5.1

[Drew Van Order <dvanorder@DTTUS.COM>]

     Greetings,

     In our test lab, we upgraded NV6000 to 5.1 from 4 on top of Transcend
     Enterprise Manager 4.2. We now wish to uninstall, and Transcend's
     deinst.scr informs us that we must trick Transcend into thinking NV is
     an older version (5.1 is unsupported, so deinstallation fails). Where
     do we set this environment variable, and what syntax to use?


     Thanks,


     DVO
