Read both version fields
The cited patch notice lists two different values: App Ver. 1.17.2 and Regulation Ver. 1.17.3. Do not expect the numbers to be identical, and do not compare a regulation value with the app-version field.
| Title-screen field | Value in the October 20, 2026 notice | Use |
|---|---|---|
| App Ver. | 1.17.2 | Compare this with the App Ver. line. |
| Regulation Ver. | 1.17.3 | Compare this with the Regulation Ver. line. |
| Platform list | PS4/PS5, Xbox One/Series X|S, Steam | Do not extend this note to Switch 2 without a Switch-specific notice. |

A mismatch is a distribution clue, not a network diagnosis
Bandai Namco says 1.17.2 is required for online play. If one of the two displayed values differs, first verify the correct game's update is installed from its platform store and launch the game again. This guide does not claim a particular update mismatch explains every connection, sign-in, summon, or multiplayer issue.
- Record platform and both title-screen values exactly, including the field labels.
- Check the platform store for the current Elden Ring update and install what it offers.
- Launch the game again and re-read App Ver. and Regulation Ver.; do not infer installation from a download notification alone.
- Compare with newer Bandai Namco patch notes for your platform before using the dated 1.17.2 pair.
- If values match but online play still fails, separate a server/service or network issue from this version check and use official support.

Keep Switch 2 on its own update path
The October 20 notice names PS4, PS5, Xbox One/Series, and Steam. It does not list Nintendo Switch 2, where Bandai Namco markets Elden Ring Tarnished Edition. This is a scope limit of the cited 1.17.2 notice, not a claim that Switch 2 online play is unavailable.

When posting a reproducible report
Steam Discussions contain player-authored reports, not verified fixes. If asking for help, include the platform, store update status, the exact App/Regulation values, and the full message text. Remove account identifiers, email, and private file paths. Do not present an old thread as proof of a current patch issue.

Date and limits
The pair below is tied to Bandai Namco's October 20, 2026 release notice. A newer patch supersedes this comparison. The checker only compares text you type; no live client, server, matchmaking, file, or account is read.

Before you play
- Record App Ver. and Regulation Ver. separately.
- The cited Oct. 20, 2026 pair is App 1.17.2 and Regulation 1.17.3.
- Install updates through the platform store and relaunch before comparing again.
- Use a Switch 2-specific notice for Tarnished Edition; it is outside this patch note's listed platforms.
- A matching version pair does not prove that servers or a network are available.
Frequently asked questions
Why does the patch note show App Ver. 1.17.2 but Regulation Ver. 1.17.3?
They are separate fields; Bandai Namco's notice explicitly lists that pair.
Does a matching pair guarantee online play works?
No. It only matches the cited update note and cannot test servers, network, account state, or matchmaking.
Can I use this exact version check on Switch 2?
No. Switch 2 is not among the platforms listed in the October 20, 2026 1.17.2 notice.
