Make sure Make sure "Random hardware addresses" is turned off in Window’s settings.My Mathcad Prime license file wouldn’t recognize my computer with  "Random hardware addresses"  turned on,

NO PUDE INSTALAR LA VERSIÓN 12 DEL MATH CAD STUDENT. SOLICITO EL REEMBOLSO DEL DINERO.

I have purchased a key for Mathcad for an employee at my company. I purchased it with my computer. I am trying to get it set up on his and cannot find a product key anywhere on my end. There are dozens of codes and numbers but none that are titled "product key." Additionally, all support videos seem to be for older iterations of the website and do not help. Similar problem with the knowledgebase articles. Any help on setting my coworker up with Mathcad 12.0.0.0 Prime would be much appreciated. I can provide proof of purchase if need be.

Reference topicThere does seem to be a bug with Polyroots. I get the same error with the Quicksheet and a manually entered matrix of coefficients.If anyone can advise how to fix this issue  your advice would be appreciated. Ross 

Hi, I am trying to solve an ODE to model a “Ball and Cone” tuned mass damper. The equations simulate a ball mounted inside a pair of cones with mass on top. The ball oscillates up and down an inclined slope with a curved region at the apex between the up/down slopes. I am using Radau solver as it is a stiff equation. Adams/BDF “does not converge”. The 1st solve block uses a simplified simulation for base excitation of the TMD. Using Radau with modest levels of damping the first solve block result gives a discontinuous response which should not happen given the inclined slope is a tangent to the curved section at the apex. Any ideas how I can correct this discontinuity would be appreciated.I tried using sigmoid transition functions (2nd solve block) for the step between inclined slope and radius but this gives a large number error.The 3rd solve block includes an extra degree of freedom to simulate the tower on which the damper is mounted, which is the aim of the program. This won’t solv

Attached are two images of my solve block.The example in screenshot 192200 does not work.  🥴  I am trying to define functions to be used in the equation to be solved.The example in screenshot 192321 DOES WORK.😀  I have explicitly put the functions into the equation to be solved.NOTE:  I cannot define the functions with the MATHCAD:= because I later use the solve block to compute a series of 𝛼 for a series of the parameters inside the Ans(….).Is my non working example simply not possible, or do I have some syntax or logic error? Thanks for any help.Reg  

Team,I need to automate this for sequential integer values of n.Any ideas anyone?Thanks,Glen

I want Mathcad Prime 11.0.1.0 to solve a simple exponential integral and it returns a limit towards infinity no matter what kind of assumptions I give it. A negative exponential should always go to 0 for x towards infinity when tau is real and positive.If instead I substitue manually a new variable x  the integral is solved correctly How can I convince Mathcad to do the same ?

Hi there , I’m using mathcade prime 11I need to get the max values using max function regardless if there are positive or negative , how ever when I use [ I x I] I get different numbers , how can I get the max ? Thanks 

I am a student  and ordered Mathcad Prime 12 Student Edition. I verified that my credit union account was charged. I followed all of the linked steps in the email I received and got an error message: Access denied - Insufficient Privileges Our records indicate that your company does not have a current PTC Global Support agreement I have phoned and emailed Cleverbridge and have not had any luck in getting them to fix this issue. They incorrectly believe I have a billing problem which I do not! I am unable to speak to anyone at PTC about this because of the logic of your automated phone answering service.

Hello, I was charged for the automatic renewal of my subscription, which I don't want. Is it possible to request a refund? My order number is 538773813. I have already canceled my subscription, and I regret that I cannot provide the activation key for my license because it was not included in my payment confirmation email.

When trying to obtain the trial version of Mathcad prime the page says that my UK phone number is invalid and will not allow me to proceed. The country is set to UK.

I’m using PTC Mathcad 10.0.0.0 (as of May 2026).  Is this the latest version?   How can I determine if there’s an update?  Where do I check?  In the software?  Somewhere on this website?   Thanks

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.

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

I am looking to define the variable ϕ2.min based on the table below. I have created the variables for HC and HD to define them as HC1 and HD1 etc. however I am not sure how to then pull a value for ϕ2.min based on the below selection table.  Any advice here would be great!  

I am trying to specify the value of a variable based on the value of a second variable. The attached table shows what I am attempting to achieve is setting the value of B2 based on the value of d in-line with the data attached. Any help will be appreciated. Thanks 

We run FLEXnet on our company license server for Mathcad licenses. Currently on version 12. Our Mathcad license file has both permanent and subscription licenses of Mathcad Prime (and 15) in it. When a user runs Mathcad, the server first assigns a license from the permanent pool. If that pool fills up then it assigns a license from the subscription pool. The problem is when a user receives a license from the permanent pool, the license type shown within their Mathcad software says Home Use when it should say something like Commercial. This results in certain calculations being inaccessible and causing errors in their worksheet. But if a user receives a license from the subscription pool, the license type is shown as Subscription which should be fine.I would like to know why our Mathcad license server is serving us Home Use licenses instead of the commercial licenses we paid for, and how do we fix this?

I am trying to copy a 1xn matrix developed in mathcad prime 11 and paste it into an excel like table in ansys mechanical to build material curves for stress analysis.  I cannot for the life of me figure out how to do what seems like a simple task.  Is this an easy thing to do?

Hi,I have a file that can’t be opened by Mathcad Prime.I just get the message “File type not supported”.Anyone got any tricks to find ways to repair the file?I attached the file here in .zip format since mcdx format is not supported.

Hello, i have problem with installation of mathcad. I couldn't go next from ,,Aplication Selection'' window so i haven't installed mathcad yet.Thanks for help.
