I am trying to install MS 8.1.1 I bought sometime ago. I don't remeber if I installed it on any of my two computers. So I tried to reinstall. However, I was told on both PCs that I need to remove the evaluation version first. Does this means I have not installed it before. In the start->programs->National Instruments I do see MS 8.1, but I can't tell if it is eval version or how to uninstall. I also can't find the program from the pc's control panel (MS is not listed here).
