Licensing Issue

[AA_10125100]

I've received a file named "sw_license_email_5559049.dat" from email ID "mathcadlicensing@ptc.com". Can you tell where should I copy paste the file and the following procedure? I cannot open .dat file saved in my PC but I can open it through email.

1. What version of Mathcad do you want to install?
2. Use Notepad++ to open ".dat" files: https://notepad-plus-plus.org/downloads/

1. Although I'm using PTC Mathcad Express Prime 7.0.0.0, I don't mind installing other versions.

2. That helped, thanks.
