I am not sure if this applies to your situation, but I had the same error. Here is wha I was running: Host was OSX 10.10.2 (Yosemite) vmware guest was windows 7 and windows 8.1 (didn't matter) I was installing JSS to the windows guest. I received the same keystore error. Turned off sharing from guest to host (turned it completely off - one checkbox) and error went away. I tried everything else before regarding the keystore. Gen a new one etc. Nothing I could do to get it to work. I am not sure if this means that installing on the mac would fail in the same manner, but the windows guests now have everything installed (and running when sharing is off)
