Mathcad Prime 2.0 Help does not work - HTTP Error: 500

In my company we have a floating server license for Mathcad Prime 2.0, I just got a new single license for my computer and I've asked an intern in Europe to download a 30 day trial version. Result for all of these: Mathcad Prime 2.0 help does not work and returns a Java.lang.nullpointerexception error.

I filed a case and have been through hours of uninstalling and installing Java versions, turning on and off McAffee (not really appreciated by our IT folks), uninstalling and installing the Mathcad Prime program, rebooting the system and so on. Nothing makes a difference. Upon searching the internet, it appears that this particular error can only be avoided by correct programming. So, here I sit with a brand spanking new Mathcad Prime 2.0 program, ready and eager to use it, but what is one to do without help? Where to turn?

Since it appears to have gotten silent on my case lately, I turn to the broader community. Is there a way to get the help files in PDF form or even on paper, so I can do something till the programmers have fixed this error?

Any help appreciated, 🙂

Peter

Peter,

We do not have the Help in PDF form.

I will follow up on this for you. Is this an issue for both you and your intern?

The only thing I see in the support database is this:

In Mathcad Options> Options, un-check the "Use Help at an alternate location".

Regards,


Mona

I have exactly the same error on my Dell laptop running Win 7 Pro - the software was just installed, and the help is giving me the same error. Updating Java had no effect on the error. Perhaps you or someone from PTC could post the fix to this problem.

If I understand Peters posting right it should suffice to edit the file launcher.xml in the Help directory of Prime and change the line

<sysproperty key="dmc.temp.dir" file="c:/temp"/>

so that it points to a directory you have rights to write to.

Thanks for the information - but this method did not solve the problem. This key was commented out in the original launcher.xml, and inserting the key as written above made no difference, whether it points to c:/temp or another folder created by me.
