Hi everyone,
I’m currently looking into installing Business Central version 28 (2026 release wave 1)

However, I initially encountered a 404 – File or directory not found error.

Link: What's New or Changed in Business Central 2026 release wave 1 - Update 28.0 preview - Business Central | Microsoft Learn

Has anyone else experienced this issue when accessing the documentation for version 28?

Is there an updated or alternative link for installation guidance (especially for on-prem)?

Are the installation packages or docs not yet fully available for version 28?

From what I understand, version 28 is part of the 2026 release wave 1 and may still be in preview or rolling out , so I’m wondering if that could be the reason.

Any clarification or guidance would be greatly appreciated!

Thanks in advance!

404 - File or directory not found.

Hi,

Yes, I am facing the same issue. Most probably the reason is that the update has been postponed and we currently do not have a resume date for the same.

You can check this link to know when the updates are resumed - https://yzhums.com/37293/

Do mark as verified if this helps.

Microsoft mentioned this in its documentation.

Hello,

Yes, this is a known/expected situation right now: the v28 “What’s New” page is live, but for on-prem Microsoft explicitly says the download packages are temporarily suspended due to a known SMTP attachment issue, so a 404 on the direct download.microsoft.com ZIP link is consistent with that and doesn’t mean you used the wrong page; for install guidance, use the official Update 28.0 page plus the v28 upgrade/install docs and the update list for version 28, but for the actual on-prem media you’ll need to wait until Microsoft republishes the fixed builds.

Regards,
