New PC installation of Mathcad 14.0, license.dat creation issue

I own a perpetual Mathcad 14.0 M020 Single User license purchased directly from PTC. The legacy MCLicense.exe utility authenticates to my PTC account, but the activation request fails with HTTP 403 Forbidden before a license.dat is generated. Since license.dat is never created, Mathcad reports that C:\Program Files (x86)\Mathcad 14\licenses\license.dat does not exist. Can someone generate a replacement license.dat or License Pack manually?

My old PC crashed so I am unable to locate the old file.

Of course this also applies to Mathcad 14. You'll have to contact PTC license support directly. This forum is for and by users of the software. Cannot help you with licensing.
