Is there a possible way to open a Javelin document through a Chrome OS?

Not for the Drumlin/Javelin offline PDF security system – however, it is possible for our Managed online secure PDF access, as for example: http://drmz.net/c001/World/index.html.

That is, unless you can run Windows on top of Chrome OS – see a discussion of this issue at: http://www.howtogeek.com/173353/how-to-run-windows-software-on-a-chromebook/ and so there are options, but not a direct native Chrome OS version of Javelin.
