How do I get the migration assistant add-on?

Mth2026 — Sat, 25 Apr 2026 19:36:44 Z

I have installed Maple Flow 2025 as a trial but have not been able to get the migration assistant add-on.

As part of evaluating Maple Flow, it is critical for me to try conversion of Mathcad 14 files.

Thanks.

Wrong root of sinc expression

C_R — Sat, 25 Apr 2026 08:27:51 Z

Here is another case where an incorrect solution of a non-algebraic expression is returned.

How to make Maple exclude solutions obtained with allsolutions where the expression is not defined?

IMO, allsolutions facilities of Maple should do this automatically. Anything from a mathematical point of view that speaks against an automatic exclusion?

(Are there other commands that provide a correct solution?)

By the way:

solve(sin(x)/x)

does not return a single solution as stated on the solve help page ("In general for transcendental equations, the solve command returns only one solution,...") because solve correctly discards x=0 but does not consider returning x=pi.

(1)

The above expression is not defined at

(2)

Error, (in value/Eval) numeric exception: division by zero

Originally _Z1, renamed _Z1~:
is assumed to be: integer

(8)

The above should be false because is not defined for However, this is what automatic simplifcation does behind the scenes with the output (7)

(9)

For this particular case Maple should have returned a special name expressing nonzero integers, like .
or or are common symbols for that
So is incorrect in the solution and automatic simplification does something wrong.
Only substituing everything at once leads to a correct response:

Error, numeric exception: division by zero

Again is not a valid solution for the first solution butworks for the second solution

Substituing everything at once works

However, the second solution does not cover all solutions (it misses even multiples of π)

Maybe adding new convert form is an option.

reading and writing

I calculate a long polynomial p(x) where the coefficients depend on a varaiable d. That takes about 10 minutes. I put a colon at the end of the computation because the result is very large. Then I put d=12.2 say and proceed to do a lot of other things. All well and good. I save the file as fooapril23 and go home. When I return I want to repeat the computaion with d=12.5 which I can do by opening the file, saving it as fooapril24. Then I have to recalculate p which is 10 mintes wasted until I can say d=12.5 and proceed with my work.. I would like to "park" the result for p in a file somewhere and then import it when needed. I went to the read and writeto help pages but could not understand it at all. (I tried bit when I did the writeto command and then opened a new worksheet and tried to read I got an error:

Error, on line %1, syntax error, `>` unexpected:

(The > was the Maple prompt I guess.)

I have tried over the years to use the writeto and read commands but I think the help pages are written for unix gurus and I am a Mac user.

BTW I am using Maple 2026 My worksheet starts with > restart; Digits:=20: with(Plots):
I guess requiring the with(Plots): command in 2026 is some kind of an in joke?

license error starting OpenMaple session

goebeld — Fri, 24 Apr 2026 13:44:22 Z

I do have a stundent license permanently and I've installed the OpenMaple java examples: JCEngineCallBacks, JCHelpCallBack, jcmaple in Eclipse.

I've also installed the MapleTest.java which runs fine.

When I start the jcmaple.java I get the error: license communication problem 1 Error starting OpenMaple session

So I don't know why.

Meanwhile I was able to solve the issue

Maple 2026 crashes. I had to use this

Is that issue known?
