I am trying to compute the equivalent annual percentage rate (APR) for a series of variable deposits with variable returns.Using the “find” function results in the error message “No solution was found...”. I tried opening up the TOL value, that didn’t help. So I tried the “minerr” function next and a different error message is displayed “Indexed assignment...”, My questions are:Which of the two errors is relevant? Can I solve equations with indexed constraints in a solve block?MP11 file is attached.Thanks for your help,

i installed mathcad prime 11 in the computer but the version that i have purchased is mathcad prime 12. I would like to request for the installer for mathcad prime 12

I am using Mathcad Prime Release 9.0 and Datecode9.0.0.0 How would I solve this equation in mathcad: y’=(A’c*l1+A’c*l2+wcb*y’2/2)/(A’c*2+13*y’) where A’c=5.336in2, l1=26in, l2=18in, wcb=13in and y is in inches Tried using the solve block but getting errors saying variable A'c is undefined. Can solve it without units and entering the variables manually but assuming there is a better way.

Have a good day, community. I have a problem with solving a vector-type equation. The issue is that the solution only returns the last result, ignoring the previous calculations. Could someone please help me? I’m uploading the file in Mathcad Prime V.10. 

Hello Ladies and Getelman, I am a student of the TU-Wien in engenering. I really like the Cad lessons and have great fun creating parts and assemplys with Creo butrecently my licensestoped working. I tryed activating it again with the installation guide providet by the TU but every time i try to put in the licencing Code It just says Error (Fehler!). I asked my proffesors about this and they just sayed that it looks like they can´t do anything and i should figure out a allternative like working on the projekts from a friends PC. But a have a assiment due the 24. and every student got a differnet one so i would have to make everything again with took an entire semester with 4 weekly hours each and many more at home. I don´t know what i can do, maybe i am just to dumb to install a new license. I would really appriciate a repply with a solution to my problem if there is one. Thank you either way for listening to my problem. Thank you again- Matthias Eder

HI i dont know who i cant convert the file from xmcd to mcdx. can some kind soul help me to convert it ?

how can we convert xmcd files if converter is not working, is this a bug any workarounds?

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
