Mac OS X 10.11 now supported

We have just released updates to Maple 2015 and MapleSim 2015 that fix the problems on Mac OS X 10.11 (El Capitan).  If you want to use the new OS, you should update your products.

Re-Installing Maple 16...

Hi all,

I'm going to call support tomorrow morning, but I figured I'd ask around here in the meantime. Thanks!

So I paid for Maple 2015 and accidentaly mistyped my email address.  I was wondering if there is anyway that I can resend the same download to the correct email address.  If anyone can help this would be greatly appreciated.

Maple 15 on Windows and Ubuntu in a dual boot syst...

Hello,

Is it possible to use Maple 15 Student Edition with the same license information and purchase code both on Windows and Ubuntu?

I did a few Windows reinstalls (guess about 3) hence I used the same purchase code to activate the license that many times. Today I tried installing and using Maple 15 on Ubuntu 12.04.3 LTS 32-bit and to my dismay the license manager said, "Not enough activations left on this account." Furthermore, I have exhausted my download links and would like to know how many times Maple 15 can be activated and if the download links can be refreshed?

Thanks

Can't install maple 17 ...

I downloaded Maple 17 student eddition for linux and when I click on the bin file to install it I get an error that says "This file is of unknown type". It gives the option to find an aplication local or online and it says no aplications available or the "MIME" file type canot be installed on this system. Im not sure what to do, do I need somthing to unpack the file or is it just not aplicable on my linux operating system (version: Cinnamon version 1.8.8 LinuxMint: olivia(X86-64))?

I have Maple 15 and I am transferring it to a different computer but I cannot find the download link anywhere. Where would I find it? Thank you!

Hi guys,

Is there any easy way to download (or upload) several files in my maplecloud simultaneously. I seem to be able to highlight several files, but when I control-click it then only selects one.

Thanks,

Units Package doesn't handle Celsius to Kelvin?...

I put Celsius in my equation and I get the wrong answer even though I've loaded the Units Package:

I have to put in the conversion to Kelvin by myself to get the right answer:

What am I doing wrong?
