Final Version 9 Updates 

The files below are ZIPs of specific programs that have been updated since the general 9.5.0.3 update. These are the final updates to these programs.
Version 9 and previous versions are no longer maintained and are offered "as-is".

  1. Make a backup of the original programs (in \MPO\PROGRAMS)
  2. Extract the contents of the ZIP files to \MPO\PROGRAMS

MPO Connections (9.5.0.8) 2009 July 21
MPO Canopus (9.5.0.14) 2009 October 21

If you upgrade one MPO program to version 10, then you must upgrade all other MPO programs as well. Because of fundamental changes to core data files, it is not possible to have earlier versions and V10 reside in the same directory tree.

If you have questions, please send an email.


Upgrading to Version 10 from Previous Versions

Due to significant changes with the implementation of a new database engine, simple updates from previous versions are not available for version 10. A full installation, with some conversion of old files, is required.

If you have questions, please send an email.


Free Updates for Version 10 Owners

From time to time, updates are offered at no charge to uses of the current version. These are available at the links below.

"Free" means that there is no update fee from BDW Publishing. Any costs associated with downloading the update files (e.g., Internet connection chargs) are the responsibility of the customer.

Click on the appropriate link and save the file (a ZIP file) to your hard drive.

  1. Unzip the Windows Setup file (an EXE) to a temporary location.

  2. Run the Windows Setup file

  3. Delete the ZIP file after you've checked that the installation worked properly

The Help and manuals are not always updated with each release.

v10.7 updates do not include the UCAC4, CMC-15, or latest APASS catalogs (DR9).
These catalogs are available for free download. Contact Bdw Publishing for details.
