REQUEST TO GET LICENSE KEY FOR MATCHCAD PRIME 2.0

I had problems with the setup crashing because kernelbase.dll as I found out in the Manage My computer My path/username contains the Swedish letter 'ö' :  ...but when I moved the extracted install-zip for MathcadPrime 9 directly to c:\ and tried to install it worked fine!Setup now runs smoothly. So be aware of any local charachters in the installation-path!  

hello. I am trying to make a combo box with multi choices of various equations depending on defined variables, the attached file will explain it very well.how can I make it work?thanks, 

In the attached Prime 8 file I'm trying to solve a problem I have invented in my head.  I have 2 metal plates, one is fixed and the other is moving toward the other very rapidly (e.g. 1000 mph).  The voltage between them varies sinusoidally at 60 Hz.  The air between the plates is assumed to breakdown at 3 kV/mm.   I want to vary the phase angle of the applied voltage and find the phase angle that results in the maximum voltage stress across the air in the gap.  But, I'm not sure how to find that maximum in MCAD.    

Using Mathcad 3.1 under Windows 10.  Mathcad refuses to plot a two-variable function even though it will plot the same one-variable function with the other variable fixed.  "Cannot plot this function. It must evaluate to real values."  What is going on?  (File attached) 

Can someone please explain how the right side (RHS) of the equation below represents active power (P)?                       Explain P: = PFUL*MVA + (MVA - PFUL*MVA) *i/N   given N = 2000, and I run from zero to N.        

Is PTC planning to offer in future versions of Prime backward compatibility with files created with Matcad 15?     

Good afternoonI`ve received License file on my email but I don`t understand how to apply it. When I use .dat file for activate nothing happens. I still see "29 days left".How fix it?

In attached file I'm trying to plot a function of time but am getting a "Replace complex values and NaNs by real numbers".  If I include units in my "t" range definition I can plot my second function.  If I exclude units I can plot my first function.  But not both at same time.  I can't see what is wrong.   

HiI get an error in the root function when a variable exceeds a specific number. See attached file.  Thanks in advance      

For x,y kind of dataset, it is required to perform numerical integration w.r.t. x'.The italiczied P represents Cauchy's Principal Value. Limits are from 0 to infinity.It was first tried to approximate the x,y data by combination of mathematical functions but didnot succeed as the data can not be modeled so easily and exactly.Apologies for not putting very clear image. I do not find any clue how to proceed on it. Thanks. 

I am analyzing a ground motion applied to a SDOF structure and finding the motion with Newmark's method. To accomplish this I have read the ground motion in with the readexcel function and then use a for loop to find the relative displacement, acceleration and velocity for each time step. The file used and the needed excel file are attached.     

Hello all, I recently got an error message when I opened Mathcad file, attached below. Error message saysAre there any means to resolve it? Thank you so muchKind regards   

Is there a way to get the plus minus sign ± into math field? I couldn't find it from the symbols list so I guess the only way of getting it into the document is to copy+paste. However, Mathcad doesn't allow me to paste it into math-field, only to text fields...

When installing Mathcad Prime, in the third window the application selection menu is empty. I've run the .exe file as administrator and the problem persists. Any help would be appreciated. 

Hi,We have an old LMTools running providing an license for MathCad 11.I would like to transfer the license to a new supported server, but I'm stuck with the license file itself.I did manage to start the license server, but I'm receiving an error: (mathsoft) Invalid license key (inconsistent authentication code)I cannot find any contract, customer nr or anything, so I cannot create a case with PTC.Can anyone help to transfer the license to a new server?Thank you     

Is there an option to make default input type text and not math? I'm doing a machine design course and we have to use Mathcad to calculate the exercises. Majority of the document will therefore be text so it would be more convenient if it was the default option. Meaning that if I just start writing, it'd write text and not math. Math-field could then be activated using [ctrl] [m]

Hello everyone: I have a question about how mathcad prime handles the units in the background. See attached Mathcad Prime 3 spreadsheet for reference. Why does the top formula (i.e., the one where the variables have units) get a different answer than the bottom formula (i.e., the one where the variables don't have units)? Shouldn't it be the same since, in this particular formula, all of the units cancel out? And how is this program handling the units in the background? Does it use default units under the hood and then convert from those default units to whatever units you type in? Thanks in advance for your replies.

Hello there,I am new to mathcad and in my start I got a strange result: I am deviding a length of dimension m by a constant number and the result is not what I was expecting    H:=10 m soil layer thickness N:=5 number of calculation layers Dz: = H/N Dz= 400        

PTC must have the most user-unfriendly support site I have seen. I want to check the expiration date of my current Mathcad support agreement, and even after logging into my account at tpc.com/support I cannot find that information. How can I check the date? If I look at the "extra" license file, it has an expiration date of 30-APR 2023.  Is that the same as the expiration date of my support agreement or does the license file have a grace period? Victor Roberts   

I have a permanent license for Mathcad Prime 3.1.  My laptop motherboard on this computer failed.   I've replaced the motherboard and can no longer use Mathcad.  When trying to get another license, I can't, since the software on the PTC site indicates that my product code is incorrect.   I'm currently retired (2016), and would like to get this working.   I'm not paying support, since I'm happy with the current versions Mathcad 15 and Prime 3.1.   Can someone guide me to the right person/contact? Thanks!Larry Callis 

Recently I have been having an issue where MathCAD Prime will nto run on my PC anymore. It loads the splash screen and then nothing happens afterwards. Looking at the task manager, a PTC MathCAD process begins but disappears when the splash screen disappears. I have followed the steps in the other relevant forum posts (below) and contacted PTC technical support for help with this issue but the only fix was to completely reinstall windows. Uninstall/Reinstall does not help, nor does copying config files from a PC where the software is still working. Compatibility mode does not help either. https://community.ptc.com/t5/Mathcad-Installation/Prime-4-0-does-not-run-anymore/m-p/803946https://community.ptc.com/t5/Mathcad-Installation/Mathcad-Prime-does-not-launch-after-the-initial-splash-on/m-p/729884 Now, 2 months later the same issue is happening again. There are no other issues with my computer, everything else runs fine except MathCAD Prime. It does not matter whether it is

I am unable to acquire a new license for Mathcad express after changing the laptop. With no access to license management, how do I get an updated license with the new Host ID?

Does anyone know how to speed up MCP for processing large data sets? I am working with a 50832x14 size data set that is output in Excel from another program. I would prefer to filter, sort, and manipulate the data in MCP vs Excel. However, trying to execute a simple filter step in MCP on a data set this large has proven impossible. I can't get the function to complete (endless spinning wheel). Whereas I can complete this one step in Excel in about 1sec. Does anyone know how to speed this up? Or any other tricks for processing large data sets in MCP? I would really, really prefer to avoid Excel but at this point, I'll have to use it.Thanks!     

In the thirty-day trial.  Hoping this "bug" (see attached .pdf) turns out to be my mistake, because if not, PTC will have lost a customer.
