I use JSON almost exclusively. A verbosely formatted JSON file is more readable than an INI file. Also, With JDPowell's JSON library, saving and loading any LV type is a breeze.
Thanks for reminding me. I just tested it and yes the TDM Importer Version 18.0.1.7167 (as reported in Excel) now imports my TDMS files without crashing. That was a major pain because I'd uninstall TDM 18.0.0, reinstall TDM 17.x, but in the uninstall some other dependencies were removed which then needed to be reinstalled...which by default installed 18.0.0 again. Oh and it looks like the download page to this add-on was updated yesterday to the new version too. Other fixes in SP1 I've heard are related to VIMs but am unaware of the details.
I've posted this before but I can't seem to find where now. This is a VI that will read the Windows registry and return the development, and run time versions installed, along with the "Current" version, which is usually the last development version opened.
