Mathcad 4.0 crashes after sending input vars from a client application to Mathcad

We have created some windows programs to control input-Vars in prime 3.1 worksheets. This worked fine for Version 3.1 but not in 4.0: Mathcad prime crashes after sending some input vars. The error message refers to a corrupt heap. The automation dll of version 4 was referenced.

 

To verify the issue between Mathcad 3.1 and 4.0 I have created a worksheet in Mathcad 3 and imported that to Mathcad 4. I have also created two client-applications, one referencing automation dll of version 3 and the other to version 4. The line ClientApp3+Mathcad3 worked fine and ClientApp4+Mathcad4 crashed. The worksheets had identical content.

Is there a bugfix available?

 

Mathcad Prime 4.0 Version: F000 (2017.02.26.001/4.0.0.54)

There is a Prime 4.0 M010 (https://community.ptc.com/t5/PTC-Mathcad-Blog/Announcing-PTC-Mathcad-Prime-4-0-M010/ba-p/475243 ), but I doubt it will solve this problem.

I have tested it with M010 but the issue is the same.

Its solved on my computer after installing the 32 bit version of Mathcad prime 4 instead of the 64 bit version.
The reason of that issue in 64 bit is unknown.

Thanks all!
