NI MAX errors with Windows 11

[SolPS]

Hello everyone,

My application recently started stopping and becoming unresponsive in the middle of a test and when I check MAX, I noticed it was too slow to open or was simply unresponsive.  I recently upgraded my OS from Windows 10 to Windows 11 64 bit but I've been running my LabVIEW 2021 32 bit application for sometime without issues but recently, I've been experiencing problems with NI MAX. NI MAX started becoming unresponsive in the middle of test execution and subsequently throwing errors. Sometimes, some COM ports will be missing from the pull-down menu.

I was only able to get things working again by resetting MAX configuration data but that has proven to be a temporary measure because the problem always reoccurs again. I installed the drivers as referenced on the Windows 11 compatibility tables.

Currently, I have the following drivers installed.

NI VISA  - 2022Q3 

NI 488.2 - 21.5.0

NI Serial - 21.5

The NI MAX errors include MAXVISATimeoutError and MAX Database connection error shown below.

MAX Database connection error

Also, after uninstalling NI VISA 24.0 and reinstalling NI VISA 2022Q3, the version displayed on MAX still shows version 24.0. Could this be part of the problem? NIPM shows version 2022Q3.

Any assistance and recommendations will be appreciated. Thanks in advance.

Hello!

It looks like you need to uninstall the Visa Runtime and any other Visa packages you may have installed. Uncheck the “products only” box at the top of the package manager to see everything. Mismatched versions can cause issues—you will want to make sure that the driver versions used in your app are the same as the LabVIEW version. You can also reset the config database by going to tools -> reset configuration data.
