Mathcad

I am a long time user of pre-Prime MathCad and have until recently been using MathCad14. I had a quick test drive of Prime when it was first launched and hated it. For reasons beyond my control, I have had to do a fresh re-installation of Windows 11 Pro. I have reinstalled MathCad but now I am unable to register its licence (“Error 403 - Forbidden”).Can anyone confirm if I should be able to continue using my old MathCad? Or has the licensing for this been discontinued? 

Hello,  Moving to Mathcad Prime 9 from V15, and noticed there are no rules or guidelines to align the different regions of the document. Any suggestions/tips/tricks to align the regions other by eyeballing them?

Snapping to the grid is not a good alternative to being able to align a group of regions.  It was very easy in Mathcad 15.  

I am trying Prrime for the first time today. How do you align regions vertically? I know how to do it in M15, but I can not figure out how to do it in Prime. I also can not find in the help guide.Thanks Andrew

Hi, I recently changed the motherboard on my PC, and my Mathcad15 licence is no longer valid. Impossible to tranfer it to a new host ID, PTC does not recognise it. I have Mathcad prime 3.1 licence, working well, but the converter from .xmcd to mcdx does work without Mathcad 15 operating. I need only 6 files to be converted.My question is if anybody having Mathcad 15 and Mathcad prime 3.1 installed could kindly do this conversion for me.I join a ZIP with the filesNote that Prime 3.1 version is required, More recent versions might deliver .mcdx files not readable with 3.1 version. I’ve read that somewhere on this siteThanks in advance 

Mathcad Prime 10.0.1 correctly read cells from Excel which includes multiple lines (<ALT>+<Enter>), displaying de read content in several lines within Mathcad.The correct interpretation of <ALT>+<Enter> was removed in Prime 11 and 11.0.1.Formatting the displayed way of the content of read values, without this change of lines, is impossible.Is this correct interpretation restored in Prime 12?

Trying to solve a large linear algebra Ax=b problem using Prime.The x:=lsolve(A,b) says not enough memory, but I can solve the same size using other software on my large 128GB of RAM.Prime 11 reports in task manager as only 217 MB.How do I give Prime access to more memory if possible?Cheers 

Hi people. I followed the program and installed the student version of Mathcad but can not start it on my computer. Any advice ?

Not able to register Mathcad 14 licence in the PTC portal. Received error 403

I could not find any other support, so I decided to write the message here. I am a student and our school uses Mathcad 11. I received a code for Mathcad pro from my teacher, but I am unable to activate it. I downloaded the software and it shows that I have the free version, and that I can activate the pro version by clicking a button on the top right. I did that and got to the licence assistant. I logged in and put the code in, but it gives me an error message "server error" after I try to install the licence. A link leads me to here: "https://support.ptc.com/appserver/support/account/contact_customer_care.jsp", but I either don't get any help from there, or I am unable to access it due to not having the correct web account. I am unable to upgrade my web account, because I don't have the data required to do so. The only thing I have is the code and the need to get this app so i can work with it in school.

When I try to download my licence to install the 30 days pro version of Mathcad a Server error shows up

Maximum trial for licensing has been end but acquisition has not been done.

Sir Isaac Newton   This month’s challenge is inspired by one of the great unsolvable challenges of physics, the Three Body Problem.  Of course, we won’t be asking you to perform the impossible in Mathcad Prime. Your challenge, should you choose to accept it, is the Two Body Problem for orbital mechanics. Earth-satellite two body problem   Challenge 1: Create the math functions and programs that can calculate the position, velocity, and acceleration of a Mazda Miata-sized satellite in orbit around the earth. (Why a Mazda Miata? It was my first and only car. Feel free to substitute a car of your choice.) Choose your orbital parameters for altitude (e.g., medium-earth, geosynchronous, high-earth), inclination, eccentricity, and any other factors.   Challenge 2 (optional): Incorporate advanced input controls to change the orbital parameters.   Challenge 3: Graph the x-, y-, and z-values for acceleration versus time. Create additional graphs for velocity and positio

Hello,I finally managed to install and run PTC Mathcad Prime 12 after solving multiple installation issues.At first, the application would not start at all and crashed with the following error in Event Viewer:"Cannot locate resource 'worksheetresources.xaml'"The issue was related to the Windows display language. After changing Windows from Polish to English and reinstalling Mathcad, the application now starts correctly.However, I now have a licensing problem.When I try to activate the 30-day trial, the License Wizard first showed several "Server Error" messages. After multiple attempts, I now receive this error:"You have reached the maximum number of license requests available for your product type."As a result, Mathcad only works in Express mode and I cannot activate the trial license.Could someone from PTC please:reset my trial activation limit, assign a trial license to my account, or provide manual activation instructions?I would really appreciate any help.Thank you.

Hi  I have issues trying to plot the Moment and Shear Force diagram of the following case. Any help is highly appreciated! 🙂  

One of the things that has always been a feature of these forums is the willingness of experienced users to provide help and guidance to others.  In addition to help with how to use the Mathcad software the forums provide a place to gain advice and assistance with dealing with engineering challenges, problems that go beyond the simple application of the software to understanding the basic physics of a situation. One remaining impediment to this  feature is the inability of Prime to save a file in an earlier version of Prime; a file asking a question in Prime 10 can be read in Prime 11 or 12 but if this file is modified and saved by a later version and posted as a reply it cannot be opened unless you have a more current version of the software. This is a great marketing tool--”Here’s your answer.  To view it you must buy the latest version of the software!”   But it’s a lousy way to share information.  The forum is littered with requests to modify a file to enable a specific version to

Thanks for the new option to customize the range of page numbering in Header/Footer, very useful when assembly a bigger document with several worksheets.Question 1: is it possible to link the page numbering to a running variable that keeps track of the overall numbering?I mean, first worksheet have 5 pages, then second worksheet starts on page number 6 until number of pages, then third worksheet starts on next page number after worksheet 2, etc.Question 2: does it exists a variable which provides the total number of pages of the current worksheet?

Up through Mathcad 15 it was possible to make a nice-looking parallel operator using the infix notation. It would be very helpful to make it work in Prime. 

I have been a paid subscriber to Mathcad since the late 1990’s. As a former a beta tester and advisor on new features, my interest and commitment to Mathcad is substantial. However, I am concerned about the future of Prime when I see more discussions on it not working rather than use.Yes some old problems are addressed with each new release. But installation and operation issues are starting to out number Topics on using the software to solve engineering and science problems. Even just upgrading to the new version or obtaining the new license keeps changing, adding to the frustration.For many of us, Mathcad is our only reason to use PTC’s products. Please do not make it a reason to be the last.   

Hello,I am trying to install PTC Mathcad Prime 12 trial, but the application does not start.After installation, nothing happens when I launch it. In Event Viewer I get the following error:System.Windows.Markup.XamlParseException:Cannot locate resource "worksheetresources.xaml"I have already tried:reinstalling multiple times (clean uninstall + removing all PTC folders) installing .NET Desktop Runtime 8 installing WebView2 disabling antivirus using a different network (hotspot)The installer I used is "pim_installmgr_mathcad".It looks like the installer does not download all required files.Could someone provide a full offline installer or suggest a fix?Thank you.

Hello, I  have been a paid user continuously since Version 1 back in the 80’s. In some important ways, Prime is still clunkier than earlier versions. I find I have to leave the keyboard, grab the mouse do some clicking on the document and then resume typing  to add every new region.I generally like to create my documents in two columns: equations in one, and text describing them right beside, but nicely aligned. In the old days you could type an equation, press a key (possibly it was Tab) and it would skip right and you could start typing text. Another key (return??) would take you to beginning of a new line and you could continue.  These days Tab only moves you to the next existing equation or document top, except it doesn’t even do that  if you are in a text region.How can you exit a text region and get over to the beginning of the next row without grabbing the mouse.  That is a lot of down and left arrows to press?What I would like isan easy keystroke to leave an region and go to th

I regularly use Mathcad to create calculations for stamped calc package submissions. This usually involves inserting screenshots and other images into worksheets to clarify my intent. In addition, I often need to add mark-ups like circles or boxes around points of interest or text with leader lines. I currently have to add these mark-ups in Bluebeam after printing the Mathcad worksheet. It would be great if Mathcad had options to add simple mark-ups / annotations in-program. Are there any plans to implement something like that? Thank you.
