QlikView Desktop September 2025 IR/SR1/SR2 – Severe Performance/Responsiveness Issues
Hi,
We have QlikView Server and QlikView Desktop installed on a Windows Server 2022 machine, which we access via Remote Desktop.
Earlier this year, I upgraded our QlikView installation from May 2023 to September 2025 SR1. After the upgrade, I noticed that QlikView Desktop had become extremely slow and unresponsive.
When QlikView Desktop is started, the menus and the application itself initially seem to work normally. However, as soon as I open a QlikView document, the application becomes very sluggish. On AccessPoint everything works fine.
For example:
- Clicking the QlikView > About menu can take 2–4 seconds before anything happens. - Right-clicking an object on a report can take several seconds before the context menu appears. - Scrolling in list boxes is very jerky and noticeably delayed. - In general, there is a significant delay between clicking something and QlikView responding.
At the time, I did not have time to investigate the issue further.
Today I uninstalled QlikView Desktop and installed the May 2023 version again. The performance immediately returned to normal. When clicking objects or menus in a QlikView document, everything responds almost instantly.
I then upgraded QlikView Desktop to May 2024 SR1, and the performance was still normal.
After that, I upgraded to September 2025 IR, and the performance problem immediately returned.
So far, my testing looks like this:
- May 2023: Good performance - May 2024 SR1: Good performance - September 2025 IR: Very slow / significant UI delays - September 2025 SR1: Very slow / significant UI delays - September 2025 SR2: Very slow / significant UI delays
I have also disabled the antivirus temporarily, but this did not make any difference.
Has anyone else experienced similar QlikView Desktop performance or UI responsiveness issues with the September 2025 releases?
Yes, I have done all that and installed on many different environments. It's something I've been looking into on and off for many months. If you just installed it on a test machine and played around with it, you will notice a difference.
I renamed the September 2025 SR2 qv.exe to qv.exe.bak and copied the May 2024 qv.exe into the same folder, without changing the other QlikView components.
With the May 2024 qv.exe in place, the performance is back to normal.
Issue might be specifically related to the September 2025 qv.exe, rather than something like WebView2 Runtime or another shared QlikView component, fwiw.
