Toolkit C++ : prerequisites for ProIntfimportSourceTypeGet

Hi,

 I am importing models using ProIntfimportSourceTypeGet() and ProIntfimportModelWithOptionsMdlnameCreate.

Function ProIntfimportSourceTypeGet() works properly on 3 out of 5 machines.

But for same model it returns error on other 2 machines.

Code is same and model to import is same.

My guess : some libs. are missing from those 2 machines. In short there might be some installation gap.

I am sure somebody must have used the import functionality before so

any help would be appreciated.
