Your VI runs just fine for me  and gives me 1, 1, 2, 6, in the 4 numerics.

A problem I do see with that VI is that you are opening the TDMS in a loop, and it is running as fast as it can.  Do you really need to keep rereading the file that fast?

Generally, the reading should be in a case structure or event structure so that it only happens when a user requires the data to be read.

I'm glad to hear that.

I must've missed this point in your original post that you were using LabVIEW 12.  That version is old.  It pre-dates Windows 10.  I would've thought you had already installed a newer version of LabVIEW.  The first version of LabVIEW to officially support Windows 10 is 2015 SP1.

Though some people have been able to use older versions of LabVIEW on Windows 10 successfully.
