Watson, we have an interesting case of the @ symbol, Time Machine, LMU and the disappearing splash screen.
The problem was that Standalone Alias Design 2012 for Mac would not startup. There was a splash screen and then it disappeared. When you switched over to a Networked version Alias Design 2012 for Mac, it would work as expected.
Clue #1
It does have something to do with the adskflex_*_tsf.data file as noted in this other solution for Windows, but more on that in a bit.

In this case, on the Mac, there was no adskflex_*_tsf.data file in the FLEXnet folder:
/Library/Preferences/FLEXnet Publisher/FLEXnet
Clue #2
The Console displayed a Time Machine and LMU (License Manager Utility) error:

Clue #3
If you use the Terminal and use the command: ls-la, you will notice that there are some @ symbols for some files and folders. It is an extended attribute in Mac OS X and we are getting a bit closer to the solution.

I just found out that there is a @ Time Machine extended attribute that will affect all Autodesk Mac-Compatible Products except for AutoCAD LT 2012 for Mac. App Store purchases are different then the conventional Standalone licensing methods that we currently are using.
Here is that obscure reference of extended attributes in this AutoCAD 2011 solution:
http://usa.autodesk.com/getdoc/id=TS16276182
"When this folder is migrated using the Apple Migration Assistant or restored using Time Machine, these utilities save metadata onto the folder. When metadata is attached to the folder, FLEXnet is not able to create the trusted storage files required to launch and run....[your product]."
Elementary, my dear Watson.
The solution for this Alias Design user was to rename the FLEXnet Publisher folder, uninstall your Autodesk product and then re-install it. This will force the installer to create a new FLEXnet Publisher folder with the proper permissions with no metadata attribute on it. This will allow you to register, launch and run your product.
NOTE: You may also notice that if you have an Adobe *.data files in that folder, you will need to move those files from the renamed folder back into /Library/Preferences/FLEXnet Publisher folder.
Thanks to Sherlock (Platform Licensing team) and Roberto Tomarchio for sharing this tip to the community.
