Error viewing documents in WebAccess (DVA)

Good morning, I just installed GroupWise Webaccess 2014 sp2 in a Windows Server 2012r2. Is running ok but the DVA is not working with any office or PDF files, it work with some PNG or JPG.

I tried other DVAs and same issue. I suspect that the problem is Tomcat?

This is the error I get:

Unable to view 'Installing the GroupWise 2014 client.pdf'
[38445] A failure occurred in the document conversion process. The document cannot be viewed at this time.

I found something from Novell: and I tried it and no luck. Keep in mind that files where in other paths.

Any help will be greatly appreciated.

Thank you
