Hi Shannon,  As of today its a static location which cannot be changed in a supported way, and I'm not aware of any unsupported way to do it either. MokaFive have a change request to allow this to be customized but its not something that is currently roadmapped.  Thanks  -Keith
I happen to be quite knowledgable on Moka5 but for some reaon the Creator (which requires a physical machine) software doesn't allow you to change the default drive when you are installing.  So you are stuck with installing on the "C" drive.  Well thats a problem when servers create a limited "Boot" partition of 30, 40, 50GB.    I created another partition strictly for images but when I manually copy over the moka5 install folder and stop, start the vmware and Moka5 services and change the shortcut destination on the desktop icon I get a "MokaFive authorization service not found. Cannot proceed" error msg.  So I need to know if anyone else has ran into this problem.
