Meeting Schedule Assistant is available in both 32‑bit and 64‑bit editions, and you can install either or both on the same computer.

For most users, the 64‑bit edition of Meeting Schedule Assistant is the preferred choice.

It offers better performance on modern systems and aligns with the increasing number of installations of 64‑bit Microsoft Office.

You should only use the 32‑bit edition if your system requires it — for example, if you have 32‑bit Office installed or rely on 32‑bit ODBC drivers.

Tip: You can install both editions side‑by‑side. This is useful if you are transitioning from 32‑bit Office to 64‑bit Office, or if you need to test different ODBC driver configurations.

Windows 11 lists the two editions as separate apps, clearly labelled:

• Meeting Schedule Assistant (32‑bit)
• Meeting Schedule Assistant (64‑bit)

You can launch either edition from:

• the Start menu (pinned or “All apps”)
• the taskbar (if pinned)
• a desktop shortcut (if created)
• the installation folder in Program Files or Program Files (x86)

Because Windows 11 no longer displays apps in a traditional folder tree, the two editions simply appear as individual entries. No additional configuration is required.

If you synchronise data with Public Talks, the correct edition depends on three factors:

• the database format used by Public Talks (MDB or ACCDB)
• the bitness of the ODBC drivers installed on your system
• the bitness of Microsoft Office, if present

The table below summarises the supported combinations and helps you determine which edition to use.

Public Talks Database	Office Installed	Required Driver	Which MSA Edition to Use	Notes
MDB (legacy)	None / Any	32‑bit MDB driver (built into Windows)	32‑bit	Works immediately; no extra setup
MDB (legacy)	64‑bit Access or 64‑bit Access Runtime installed	64‑bit MDB driver	64‑bit	Required if you want to run the 64‑bit edition
ACCDB	32‑bit Office	32‑bit Access Database Engine	32‑bit	Must install 32‑bit Access Runtime if not already present
ACCDB	64‑bit Office	64‑bit Access Database Engine	64‑bit	Must install 64‑bit Access Runtime if not already present
ACCDB	No Office installed	Choose either driver	Match the driver you install	Install 32‑bit or 64‑bit Access Runtime as preferred

You can install both editions of Meeting Schedule Assistant, but keep the following in mind:

• Each edition can only use ODBC drivers of the same bitness
• The ODBC drivers must support the database format you are using
• Public Talks and Meeting Schedule Assistant must effectively match bitness to communicate correctly

If you are unsure which edition to use, the 64‑bit edition is generally the better choice. It offers improved performance on modern systems and aligns with the growing number of 64‑bit Office installations. Choose the 32‑bit edition only if your system specifically requires it — for example, when using 32‑bit Office or 32‑bit ODBC drivers.
