I upgraded recently from ADA 61402 (x86) to ADA 61404 (x86-64) under SLES 10. Now I’m trying to upgrade from NAT633 (x86) to NAT635 (x86-64). (I select NDV, WebIO, and Remote Debugger installation options.)

The Natural installation fails when it attempts to invoke the Buffer Pool.

When I try to invoke the BP manually via natbpsrv, I get

I’ve tried the manual Natural uninstall procedure, so SAGRM responds with

Any suggestions on how to complete the installation?
