Issue Details

I developed a project in LabVIEW to acquire data from a LabJack T4 multifunction DAQ device.

The project has been repeatedly deployed on a Windows 7 SP1 PC with no issue.

I have recently updated to a Windows 10 PC and now when the executable is deployed, I encounter error 1026.

Error -1026 occurred at an unidentified location.

This error code is undefined. Undefined errors might occur for a number of reasons. For example, no one has provided a description for the code, or you might have wired a number that is not an error code to the error code input.

Additionally, undefined error codes might occur because the error relates to a third-party object, such as the operating system or ActiveX. For these third-party errors, you might be able to obtain a description of the error by searching the Web for the error code (-1026) or for its hexadecimal representation (0xFFFFFBFE).


As of the 1st January 2019, the 'LabVIEW for LJM - Windows' Device driver is not compatible with Windows 10.
