Re: Ugrading Networker client fails : installer error status 1603
Rename the ~nsr/res/nsrladb directory and retry. I hit this issue during upgrade of a bunch of storage nodes here.
Oh, the "no changes have been made" is complete bull during an upgrade. The previous version's gone, and your 2nd install attempt will pick up the default directory rather than the existing ~nsr directory - make sure you change the install location (if applicable) to keep it in the same place.
