Direct RT execute error (case 6459)

[LRoberts]

I am embedding a Direct RT file within a Media Lab file (both were created using v2012). When I try to run the files on a different computer that has v2010, the Media Lab files run fine, but the Direct RT files won't run. I get the error message below... Is this a problem with this individual computer, or do I need to edit my input file (also below)?

Thanks!
