2 Server Versions, problem with backup from pgAdmin

I have Windows 7 machine, with pg version 9.2.7 installed, listening on 5432. (pgAdmin, version 1.16.1) It is installed at
C:\Program Files\PostgreSQL\9.2

Recently, I installed (added) pg version 9.3.3, listening on port 5433. (pgAdmin, version 1.18.1) It is installed at
C:\Program Files\PostgreSQL\9.3

Both servers running and appear to be behaving normally.

However, when I try to back up a table from within the 9.3 pgAdmin (v1.18.1) the table backup fails, woth the following message:

C:/Program Files/PostgreSQL/9.2/bin\pg_dump.exe --host localhost --port 5433 --username "postgres" --role "postgres" --no-password --format plain --section pre-data --section data --section post-data --encoding UTF8 --inserts --verbose --quote-all-identifiers --file "G:\Data\apothecary_backup_20141001a.sql" --table "public.apothecary" "postgres"
pg_dump: server version: 9.3.3; pg_dump version: 9.2.7
pg_dump: aborting because of server version mismatch

Process returned exit code 1.

What this tells me is that the NEW version of pgAdmin is using the OLD version’s pgDump.

However, I can’t locate where this is defined. I checked the registry; Base Directory (for both) points to the correct folder

Would appreciate any pointers to correct this issue

Thanks
