Failed to uninstall National Instruments Software

Hello,
Recently, I was trying to uninstall the National Instruments Software but an error 1601 occurred during the uninstallation. I tried multiple times to uninstall this program but not successful. What could be the cause? Can I get the resolution to fix it immediately? I am using Windows Operating system so instruct me properly.
Thanks for help.

Error 1601 occurred. Would like to continue this operation?
