Upgrade advisory for Qlik Sense on-premise Novembe... - Qlik Community

Sonja_Bauernfeind · ‎2026-01-15

Edit February 12th, 2026: Follow-up patches have been released.
Edit January 21st, 2026: Updated the title and content to include the November 2024 release

The patches resolving the ODBC-based connectors issue post-upgrade have been released as of February 12th, 2026. Check the download page for the following releases:

Qlik Sense Enterprise on Windows November 2025 Patch 3

Qlik Sense Enterprise on Windows May 2025 Patch 13

Qlik Sense Enterprise on Windows November 2024 Patch 25

During recent testing, Qlik has identified an issue that can occur after upgrading Qlik Sense on-premise to specific releases. While the upgrade completes successfully, some environments may experience problems with ODBC-based connectors after the upgrade.

The issue is upgrade path dependent and relates to connector components that are included as part of the Qlik Sense client-managed installation.

The advisory applies to the following releases:

Qlik Sense Enterprise on Windows November 2024
Qlik Sense Enterprise on Windows May 2025
Qlik Sense Enterprise on Windows November 2025

Recommendation: After upgrading Qlik Sense on-premise, verify your connector functionality as part of your post-upgrade checks.

How can I identify if I am affected?

The issue can typically be identified by files being missing after the upgrade. In this example, the Athena connector is not working, and the following file is missing:

C:\Program Files\Common Files\Qlik\Custom Data\QvOdbcConnectorPackage\athena\lib\AthenaODBC_sb64.dll

In this example, all ODBC connectors stopped working:

C:\Program Files\Common Files\Qlik\Custom Data\QvOdbcConnectorPackage\QvxLibrary.dll

With the QvxLibrary.dll missing, both existing and newly created ODBC connections will fail.

How do I resolve the issue?

Fixes were released on February 12th, 2026.

Check the download page for the following releases:

Qlik Sense Enterprise on Windows November 2025 Patch 3
Qlik Sense Enterprise on Windows May 2025 Patch 13
Qlik Sense Enterprise on Windows November 2024 Patch 25

Stay up to date with the most recent version by reviewing our Release Notes.

Workaround

If your connectors have been impacted by this upgrade, rollback your ODBC connector package to the previously working version based on a pre-update backup. See How to manually upgrade or downgrade the Qlik Sense Enterprise on Windows ODBC Connector Packages for details.

The workaround is intended to be temporary. Apply the fixed Qlik Sense Enterprise on Windows patch for your respective version as soon as it becomes available.

If you are unable to perform a rollback, please contact Support.

If you have any questions, we're happy to assist. Reply to this blog post or take your queries to our Support Chat.

Thank you for choosing Qlik,

Could confirm, that on my test server upgraded to Nov25 , Athena .dll -

AthenaODBC_sb64.dll

is missing

Connector is not working , this is error message (pretty self explanatory)

after copying .dll from different server and qlik version (May2025). Connector is working again and data are available.

Is there any other connector which could be not working due to this bug ?

spetkov-movexm · ‎2026-01-16

For us files were missing both in athena, mssql and in main QvOdbcConnectorPackage. Multiple files were missing in the folders.

What is strange is that we have 2 completely identical Qlik Servers (both as hardware and software). We only had the problem on one of them, while all worked completely fine on the other one. There were no indications or error messages before, during or after the upgrade to indicate a problem.

Thankfully we were able to copy the missing files from the working server to the broken one and that fixed the issues. Weird that Qlik allows such a thing to happen and files to go missing at all...

janyf · ‎2026-01-16

@spetkov-movexm Would it be possible to state , which files were missing ?
My colleague checked further and on our test server (Nov25) these are still missing:

C:\Program Files\Common Files\Qlik\Custom Data\QvOdbcConnectorPackage\athena\lib\LibCurl64.DllA

C:\Program Files\Common Files\Qlik\Custom Data\QvOdbcConnectorPackage\athena\lib\LibCurl64.DllA\OpenSSL64.DllA

C:\Program Files\Common Files\Qlik\Custom Data\QvOdbcConnectorPackage\hive\lib\LibCurl64.DllA

C:\Program Files\Common Files\Qlik\Custom Data\QvOdbcConnectorPackage\hive\lib\LibCurl64.DllA\OpenSSL64.DllA

But athena is working 😄

@Sonja_Bauernfeind can you please provide us 2 txt files for NOV 2025 and MAY 2025 with a list of full paths of files and folders that should be present?

here is some simple ai generated powershell script the can list missing files:

# Define the path to the text file containing file paths
$filePathList = ".\files.txt"

# Read each line (file path) from the text file
$filePaths = Get-Content $filePathList

# Loop through each file path and check if it exists
foreach ($filePath in $filePaths) {
    if (Test-Path $filePath) {
        #Write-Host "Exists: $filePath"
    } else {
        Write-Host "Does not exist: $filePath"
    }
}

Albert_Candelario · ‎2026-01-20

@spetkov-movexm thanks for your comment, could you kindly share your upgrade path that led to the list that you shared previously. Thanks in advance.
Cheers,

Albert

Sonja_Bauernfeind · ‎2026-01-20

Hello all,

@spetkov-movexm @dobak @janyf

There is no conclusive answer regarding which files can be missing or have not been updated. This depends on the upgrade path used, meaning Qlik cannot provide a list of files.

If affected, we recommend to either:

Roll back your connectors (as documented in How to manually upgrade or downgrade the Qlik Sense Enterprise on Windows ODBC Connector Packages) and wait for the patches
or contact support

All the best,
Sonja

spetkov-movexm · ‎2026-01-20

We had installed May 2025 IR (here initially we had the issue with missing files and wrong versions, so we had to REPAIR the install. then it worked), upgraded to SR2 (at this stage all was fine, or at least we have not noticed any issues), then to SR9. Then several months later, we tried to upgrade to Nov 2025. Here the upgrade failed, since files were missing. Uninstall of SR9 failed also manually. Repair could not be launched also. Then we needed to copy the entire QvOdbcConnectorPackage folder from another server to complete the misisng files...

Or · ‎2026-01-26

@Sonja_Bauernfeind Any word on when a patch is expected for impacted versions? Was planning an upgrade for next week but I'm thinking it's better to avoid this risk if a patch is likely to be out soon.

Sonja_Bauernfeind · ‎2026-01-26

Hello @Or !

I don't have an exact date, but I do know we are working on it as a priority. Let me check for you.

All the best,
Sonja
