[PATCH] Veeam Backup & Replication 12.3.2.4165 New Patch Delivery Options

[danc]

Just want to confirm if I install the patch, will that automatically update the Veeam Agent?

When I upgraded from 12.3.1 to 12.3.2.3617 using the the Full ISO installer last time, that automatically upgraded my Veeam Agent.

[jasonede]

I also had to copy the files from the extracted ISO to downloads to get them to run.

[Gostev]

Right-click the ISO file, go to Properties, check Unblock and click OK.
Do this BEFORE you mount the ISO.

Hello,

what about Veeam Backup Enterprise Manager (VBEM)?

The notes in the patch download section mention:

If you use Veeam Backup Enterprise Manager, start the update procedure with this component. Veeam Backup & Replication should be updated after that.

However, there is no patch available for VBEM in the download section.
Can we install the 4165 patch using the EXE/ISO file even though there is no separate VBEM patch provided?

Thank you in advance for your clarification.

Best regards!

Hello gkotzur,

there is no patch available for VBEM in the download section.

The same patch exe / iso files should be used to patch Enterprise Manager installation. Thank you!

[Dima P.]

Just want to confirm if I install the patch, will that automatically update the Veeam Agent?

Yes, once fix is applied to the backup server it's also automatically applied to all managed agents during Protectio Group rescans. For 'Pre-installed agent' protection groups type and for manually managed agents you need to follow instructions in this KB article. Thank you!

The full iso just says modify, then gives you an error that the product is already installed.

The patch says this "Couldn't load file or assembly file:///g:\Setup\ServiceOperation.dll' or one of its dependencies. Operation is not supported (Exception from HRESULT: 0x80131515)."

Trying to update from Veeam B&R 12.3.2.3617.

Do I need to open up a case?

I got the similar error. Have been advised in the support portal to run the unblock-file in cmd. But that didn't work. I used Powershell as admin and ran Unblock-File -Path "T:\Temp\Veeam Installers\VeeamBackup&Replication_12.3.2.4165_20251006_patch.iso"
Then manually had to stop services and veeam.shell. Otherwise the wizard will keep throwing the error.

Finally it's in progress. But my question is unlike before this update patch doesn't show that whether it's updating the Enterprise Manager or VBR. As my Enterprise Manager is hosted on the same VBR server.

[geetansh]

Are there any known issues with SQL plugin backups after applying this patch? We just applied it and most plugin backups are failing.

[Gostev]

There are no known issues with this patch whatsoever at this time.

FYI for Veeam.

The new .exe format is not updating the version of the installed program within Windows Registry: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

We are an MSP with many installation and we use Tanium to check the version through the registry, this method has worked solid for us, up until now.

In the installed programs list in Windows, it does show the correct version though. I believe when devs uses some package installers to create exe files, they have to update the registry manually, where MSI files tend to just do this automatically in Windows. This seems to have been forgotten for this patch.

I believe I read a post 1-2 years ago where a lot of people requested an PowerShell command for Veeam to get the version, I've just checked the documentation, unfortunately it does not seem like this has been added yet (Only VBO has it?).

Is there any native way within Veeam to get current version of VBR reliable that I don't know of since I've looked into this last?

EDIT:
This method displays two different versions for VBR, the previous build and the new build:

Code: Select all

Get-Package | Where-Object { $_.Name -like "Veeam Backup & Replication*" } | Select-Object Name, Version, ProviderName


Name                               Version     ProviderName
----                               -------     ------------
Veeam Backup & Replication Console 12.3.2.3617 msi         
Veeam Backup & Replication         12.3.2.4165 Programs    
Veeam Backup & Replication Server  12.3.2.3617 msi

I use this to get the VBR version, I can't remember when it was implemented:

$version = (Get-VBRBackupServerInfo).Build.ToString()

Use the following from Veeam Powershell to check the Backup Server version:

Code: Select all

Get-VBRBackupServerInfo

Name      Build       PatchLevel
----      -----       ----------
HK-VBR-02 12.3.2.4165

Pleased to see the trend towards more reasonable download sizes!

Unfortunately, still dealing with the frustrating poor plugin design - following the patch all our servers' configuration backups are throwing the errors about the plugins we have been running into for years:

Warning Failed to connect to AWS plug-in: Failed to login to platform service: The underlying connection was closed: The connection was closed unexpectedly.
10/16/2025 10:00:48 AM Warning Failed to connect to Microsoft Azure plug-in: Failed to login to platform service: The underlying connection was closed: The connection was closed unexpectedly.
10/16/2025 10:00:49 AM Warning Failed to connect to Google Cloud plug-in: Failed to login to platform service:

Hey all,

Regarding checksums, the update exe is actually provided within a zip file, and the checksums on the website are for that zip file, not for the extracted exe. I can confirm the zip checksums match the values on the website, for the file I've downloaded.

These smaller update files are greatly appreciated, the full 12GB ISOs were a bit unwieldy! Thanks to the Veeam team!

I have one question though - a while back I put together a monitoring script that watches http://dev.veeam.com/backup/vbrupdate.vdf (which is, according to posts i've seen on these forums, some kind of official endpoint Veeam uses to track available updates) and lets my team know if we need to patch Veeam. However, it seems like it's not kept as up to date as the forums are... basically, is there a programmatic way we can watch/track updates, or should we subscribe to emails from Veeam?

Thanks and regards, Anthony

We also just had our first customer contact us regarding failed plugin backups for SQL.

Yes, we publish checksums on the website for the actual download packages and their contents. Both ISO and ZIP files are hashed.

Thank you so much for this feedback! We’ll share it with the R&D team who made this improvement possible.

I have one question though - a while back I put together a monitoring script that watches http://dev.veeam.com/backup/vbrupdate.vdf (which is, according to posts i've seen on these forums, some kind of official endpoint Veeam uses to track available updates) and lets my team know if we need to patch Veeam. However, it seems like it's not kept as up to date as the forums are... basically, is there a programmatic way we can watch/track updates, or should we subscribe to emails from Veeam?

The vbrupdate.vdf engine is designed to notify customers about new versions and updates, but we typically enable it a bit later - after the support team gives the green light to notify everyone about the patch. So, a delay in updating this file is expected. If you want to track release history, the KB article is the best option, as it’s updated instantly when a new build or patch is published on veeam.com.

Thank you!

Please share the support case IDs so the responsible teams will review and follow up. Thank you!

As mentioned previously, there is a comment "If you use Veeam Backup Enterprise Manager, start the update procedure with this component. Veeam Backup & Replication should be updated after that."

Although when running the patch there is no choice to update Enterprise Manager, just install... As we have both EM and VBR installed on the same machine, how can I perform EM upgrade first?

With classic ISO there is no option to Upgrade, just Modify.

[geetansh]

We had the same issue with Veeam Plug-ins for SQL. Backups were failing until we upgraded the the plugin to latest patch. I would suggest to please add this information to the KB article to avoid the same pain for others.

You don't, this note is for when VBR and EM are installed on separate machines.

Folks, apologies but a few latest posts are a complete off-topic to this thread about new patch delivery options. Please create dedicated topics in the corresponding subforums depending on technology you're querying about, where the responsible PMs can actually see them and respond. Not to mention it's plain unmanageable to deal with multiple completely unrelated questions in the same thread. Thanks for understanding!

[FCU_JE]

@Gostev - if I may, Mr. CPO - may I suggest we use a hybrid approach?

First - yes, absolutely bugs that are directly related to the new patch delivery ZIP/ISO should be tracked in new R&D forum threads. Second - we can *link* to those threads from this thread.

As this patch delivery is experimental, it helps to know the pain points, but it doesn't help to burden down the main thread with detail.

[Gostev]

Thing is, after tens of thousands of patch downloads there are no known bugs that are directly or indirectly related to the new patch delivery methods... so it's very unlikely any such bugs exist in principle.

[BennyDC]

Hi all,

So to be sure this patch is only for VBR and EM, there is no patch for Veeam ONE?

[m.novelli]

Hello Daniel,

The "Update Remote components automatically" wizard should be displayed after the patch is installed, you need to reopen the product UI to see it. Thank you!

Quite uncomfortable updating 100+ customers

Correct.

The team is planning to reissue the patch this week with the "Update remote components automatically" checkbox returned.

[nd39475]

having noticed the "patching" was a little different i was keen to click the link to the thread.

i appreciate the new format and convey thank!

the original email that we received should have had a direct link to the .exe / .iso as i recall i had to either pan-around or click-around to find it.
