Have you updated WW6.5 for custom updates? And have you tried to run a redetection in WW6.5?
See how to do the above in their Knowledge Base here
Having recently updated Window Washer from 6.0 to 6.5. I've now noticed that certain custom software programs that had been reconised on 6.0 (ie Paint Shop Pro 9) are not 'seen' on 6.5
Has anyone else had this problem and possibly solved it?
