Hi,

When calling the Help Function in MathCad Prime 3.1 or MathCad Prime 4.0 i get the error Message:

I'm working with Windows 10 and Java is still up to date.

Has anybody an idea?

Thank you

regards, Volker

Now there is a solution found:

The problem was a NVIDEA-Driver.

After uninstalling the driver, Prime-Help works perfectly.

How do you call help (using the "Help Center" button or "F1" key) and what version of Java is more accurate? By the way online Mathcad Prime 3.1 help center available here: PTC Mathcad Prime 3.1 Help Center‌ Unlike the previous help centers available online through login the account on PTC's website isn't required now.

The error message comes up at F1 Key or at the Help Center Button.

Thank you for the Link-that works.

I see there are many problems with the Prime versions, what a shame.....

btw: In Mathcad 15 the Help works wihout any problems, so Mathcad 15 is the King!!!!

Java-Version:

JAVA_VERSION="1.8.0_121"

OS_NAME="Windows"

OS_VERSION="5.2"

OS_ARCH="amd64"

Volker,

1. Try to edit exception site list in "Java Control Panel" settings (tab "Security") and add the following (need to use forward slashes in the path😞

file:///C:/Program Files/PTC/Mathcad Prime 3.1

file:///C:/Program Files/PTC/Mathcad Prime 3.1/Help

2. Send your issue to PTC's tech support by using "Mathcad Support Center" (you can do it, even if you use Express version of Mathcad Prime):

Mathcad Support Center

Hi,

first of all I am not sure whether you can install Mathcad Prime 3.1 and 4.0 on the same machine simultaneously...

I installed Mathcad Prime 4.0 F000, launched it and clicked Help button on Resources tab. Help started without problems.

In Task Manager I can see following processes:

MathcadPrime_help.exe
javaw.exe (two times) ... MCP4_F000_LOADPOINT\Mathcad Prime 4.0\Help\jre\win32\jre\bin\javaw.exe

The above means that Help uses Java JRE available inside Mathcad installation. If I understand you well you have also your own java installation outside Mathcad. I guess that some Windows setting is the root of your problem (JAVA environment variables, system registry setting, ...)

Tip: Uninstall you "external" JAVA installation and test Mathcad Help.
