Deauthorize for reinstall

Unable to reinstall Parallels as it says it's authorized on another computer. I need to deauthorize it. Only want it one computer. I've had this problem before. Last time, no one responded to me until I posted a dissatisfied message on the forum. Again, this time, I sent an email to support and received zero reply. Please help me.

Thanks for the prompt reply. I had to delete the licenses.xml file. But, then it worked without any problem.
