Stable operation of applications on Windows 11

[kali]

Hello everyone

I have a question for my more experienced colleagues in LabVIEW programming

I use various applications supplied by a third-party company, built using LV2020 and RunTime 8.5, 2016, 2020 and VISA 4.6. Recently, I’ve noticed that various stability issues have started to occur whilst they’re running (freezing, slow performance, loss of communication via COM ports, etc.)
Consequently, I began to look into the matter and discovered that LV2020 does not support Windows 11, let alone the aforementioned drivers and RunTime.
Is there any way to run such applications stably on Windows 11 without having to modify them or rebuild them using a newer version of LabVIEW, such as 2025?

Assuming you don't have any applications installed that actually need the 8.5 or 2016 runtime, I would start by updating VISA to 2022Q3. That is the first version that officially is supported on Windows 11 and should still be fully compatible with LabVIEW 2020. That may potentially fix your communication issues, but no guarantees.

OK thanks, I’ll try this solution and hope it sorts out my problems.
But as for the applications I use: my suppliers have informed me that one of them requires the RT 8.5 runtime environment to work properly, whilst the other two require RT 2016 and 2020. In this case, RT 2022 might resolve the issues, but the transition from version 8.5 to 2022 is a very long process, and I’m not sure whether that environment will support such old applications.
