pg_dumpall -> by hand without --binary-upgrade or BUG #5690: pg_upgrade fails

In my attempts I changed all pg_hba.conf (8.4 & 9.0) to trusted, turned off firewall,followed instructions to shut down db(s) and ran cmd.exe as postgres:

C:\WINDOWS\system32>pg_upgrade.exe -p 5432 -P 5433 -d "c:/program files/postgresql/8.4/data" -D "c:/program files/postgresql/9.0/data" -b "c:/program files/postgresql/8.4/bin" -B "c:/program files/postgresql/9.0/bin"Performing Consistency Checks-----------------------------Checking old data directory (c:/program files/postgresql/8.4/data)okChecking old bin directory (c:/program files/postgresql/8.4/bin)okChecking new data directory (c:/program files/postgresql/9.0/data)okChecking new bin directory (c:/program files/postgresql/9.0/bin)okChecking for reg* system oid user data types okChecking for /contrib/isn with bigint-passing mismatch okChecking for large objects okCreating catalog dump Access is denied.

There were problems executing ""c:/program files/postgresql/9.0/bin/pg_dumpall"--port 5432 --username "postgres" --schema-only --binary-upgrade > "C:\WINDOWS\system32/pg_upgrade_dump_all.sql""
I'm not clear if it picked up the 8.4 -p 5432 and 9.0 -P 5433

And there we sit, dejected. Any thoughts would be greatly appreciated.
