Composer LitInteropSWCOM failed to load plug-in : File not found

I can load most files created in SolidWorks and viewed with Composer.

When I try to open one particularly large file I receive the following message

Composer

Solidworks Converter report:

C:\\Users\\....\\BigFile.SLDASM

LitInteropSWCOM failed to load plug-in : File not found

LitInteropSWCOM : OpenDoc failed : C:\\Users\\....\\BigFile.SLDASM

The message is confusing as it does not explain whether there is a problem with the file I am opening or with LitInteropSWCOM.

C:\\Program Files\\SolidWorks Corp\\SolidWorks Composer\\Bin exists in C:\\Program Files\\SolidWorks Corp\\SolidWorks Composer\\Bin.

Thanks in advance
