Library not Registered

[ptc-2019619]

I have just gotten back to using MathCad 14 after a relatively long absence. If I assign a value to a variable, (using and then attempt to show its value (using =), I get an error message "Library not Registered". When I tried to display the value of a built-in constant, I got the same message. Any help would be appreciated.

Easily said, but I don't know how. Could you give me a hint where to start?

After reading some other posts, I re-installed/repaired MathCad and everything seems to work now

I found the solution to this problem:

Solution:

Go to the Start menu - and open the run command box

Type mathcad /register and then hit enter, the hour glass should appear only for a moment

Launch Mathcad
