I have wrongly updated Nintex with Two Licenses. can any one help me how to remove the applied licenses and add proper licenses to the SharePoint 2013.
Thanks and Regards,
You can just import a new license which will override the former one. In case you want to backup your current license file first you can export the license on the same page.
I do not know any way to actually "remove" the current license and I don't see why you need to be doing this.
I'd agree with Philipp on this one. Easiest way would be just to import your proper licenses over the top of the messed up ones.
