when i try to install labview runtime 2016 i get the attached error.
What can i do to solve this?
It would help to explain a bit more. Are you installing on a PC running 64-bit Windows 10? Does this PC have any (other) National Instruments software installed? What are you hoping to accomplish by installing this (isolated?) LabVIEW Run-Time?
There is already a installation of NI Teststand 2019.
Runtime 2016 is needed to execute a VI compiled with Labview 2016.
