Mathcad14: "Library not registered" error

[rlmccormick]

I recently started using Mathcad 14 and have an odd issue. I was trying to solve a simple equation numerically and was given the error message shown in the subject. I have never seen this error before on previous versions of Mathcad. Here is a simple example of what can cause this error:

a:=1
b:=5

given
a=10/b
find(b)=
At this point Mathcad gives me the "Library not registered" error. Anyone know what gives? I have used this functionality in Mathcad before (previous versions) with no trouble.

Most likely problem is that the program installation isn't correct. You might need to reinstall the program.

Mathcad has always been a bit finicky about installation.

You would need to form that last line as:

b:=find(b)

Also, watch capitalization, I believe (without opening MathCAD) that given is actually Given and find might be Find.
