Hi JH Anderson,
Usually in order to uninstall everything from National Instruments, you can go to Add/Remove Programs on your computer and select to Change/Remove National Instruments software. Then select everything in that tree and remove the software.
I'm not sure if you had NI-DAQ 6.8 before this version but it is not in the Add/Remove Programs view in the Control Panel. Please let me know if this solves the problem. Thanks!
