Simscape Multibody Link - MATLAB R2017b & PTC Creo 4.0 - Error Message

Hello everyone,

I would like to use Simscape Multibody Link with Creo 4.0 M20. I have installed the software as described in the following link:

https://de.mathworks.com/help/physmod/smlink/ref/linking-and-unlinking-simmechanics-link-software-with-proengineer.html

Unfortunately, unsuccessful. When starting Creo, the following error message appears:

 Initialization of the foreign-language program' Simscape Multibody Link' failed: Error PRO_TK_GENERAL_ERROR
 Message from the foreign language program:' ERROR: pmi_api. dll couldn't be loaded'.

 Initialisierung des fremdsprachigen Programms 'Simscape Multibody Link' fehlgeschlagen: Fehler PRO_TK_GENERAL_ERROR
 Mitteilung des fremdsprachigen Programms: 'ERROR: pmi_api.dll couldn't be loaded'

Does anyone have any idea how I can solve this problem?

I use the following software:

I am not seeing any details specific to this DLL error, although some common problems that occur when working with DLLs are

1. Not being able to locate the dll
2. The dll is itself corrupt
3. The dll is not compatible (32-bit vs 64-bit).

To troubleshoot the first case:

• Verify that the dll is in the correct folder. In this case, it should be in in your matlabroot/bin/win64.
• Verify that the registry file in Creo was correctly setup, as per the documentation page you are referencing.

To troubleshoot the second:

• Unfortunately, this will like require a reinstall. From looking at other MATLAB Answers posts, pmi_api.dll is installed with the Multibody Link plugin. Try re-installing just the plugin.

To troubleshoot the third:

• Make sure Creo and your MathWorks products are running the same architecture - they are both x32 or x64.

I had this same issue today. The Mathworks' documentation you had a link for uses forward slashes. I had mixed that with back slashes when I copied my Matlab root directory in from Windows. The problem was resolved when I changed everything to back slashes.

Also, in my config.pro file, I used the command "PROTKDAT" instead of "toolkit_registry_file".
