Chrome doesn't support ActiveX so if your SCORM application creates Active X content this will not work.

Try installing the Chrome extension that supports Active X - IE tab https://chrome.google.com/webstore/detail/hehijbfgiekmjfkfjpbkbammjbdenadd to see if this solves this.

Alternatively try and prevent Active X controls being generated by the SCORM application if this is the problem.
