I'm using a Mac Pro running Sierra (however I had this problem also with earlier MacOS versions..) and I cannot open any properties files with Analyst. I have tried all possible versions of Analyst available for download on your website but I always have the same problem: the software starts, but as I click on the properties file I want to open (no matter which file) I get (pretty vague) the error message attached.
the console says this:
com.apple.message.signature: task:CommandLine version:(null) arch:x86_64
Following suggestions on your forum I have upgraded to the latest Java version with no effect.
I also have Parallels installed on my Mac and I have to say that Analyst runs smoothly under Windows 7 using Parallels, which is per se solving my problem but I'd like to be able to go through my data without necessarily running Windows all the time..
