This happens when a server instance is created with SSH connection deactivated right from the start. WB doesn't write the XML keys for SSH connections to the profile in that case - particularly the following key causes troubles when missing in profile:  
<value type="string" key="sys.config.path"></value>

This also prevents such profiles from launching admin when double-clicking the profile in the list with following output:
Traceback (most recent call last):

Bug #51522 has been marked as duplicate of this one

I had same problems under vista 32bit and windows 7 32bit. 

I manually insert the line
   <value type="string" key="sys.config.path"></value> 
in the serverInfo section of the server_instances.xml

This solves the problem in my case.

Where do I find server_instances.xml?

on window systems the file is located in your personal profile like
c:\users\<myaccount>\AppData\Roaming\MySQL\Workbench\

modified server_instances.xml for non-ssh access

This has been fixed. I believe bug #51368 which was closed first is the same issue as this, I'm marking this one as QA review because description and progress log seems more straightforward.
