Custom module functions for Interpreted Modules

Hi,

I am trying to create a Interpreted Module. In the documentation at: https://documentation.dspconcepts.com/space/DOCHUB/2748822025/Custom+Mod...,  there is a section saying that some custom module functions are supported, like the "preBuildFunc".

I have tried to create a new interpreted module  with only the preBuildFunc as a custom function. I have put it in a separated file and linked it using: "M.preBuildFunc=@preBuildFunc;"

Setting M.isInterpreted = 1  works in the AWE 8.C.2.5.A Pro version (even shows the tag "interpreted" in the module name). But it doesn't work in theAWE Designer 8.D.1.1 Standard  version. When I try to insert the module into the canvas I get the following error message: 

"Adding module failed: Previously accessible file 'C:\DSP Concepts\AWE Designer 8.D.1.1 Standard\CustomModule\matlab\preBuildFunc.m' is now inaccessible."

If I do not include the preBuildFunc, the AWE Designer accepts my custom module.

Is there anything else that I should set to make the use of preBuildFunc in the matlab module script?

Thanks in advancce,

Rodrigo
