Rosetta asks for adobe flash 10.3.181 or later, but I have v12 installed.

SOURCE: Headset Problem Rosetta Stone

I found the answer. Rosetta Stone has a problem detecting the mics if the speaker input is not in someway connected to the mic. I'm not exactly sure how it works, but I don't care and neither should you.

Follow these steps each time you want to use it and you should be fine.
*I'm on Vista, but this should work for every one.
1. Open Control Panel
2. Open Hardware and Sound
3.Open Sound
4.Set Line 1 as your Default Speaker
5. Refresh the Mic list
*All of your mics should now show up.
6. In Rosetta Stone, apply the mic you want and finish the setup.
7.Start whatever language you're using and switch back to the Sound menu.
8.Set whatever speaker you want to use as default.
*Rosetta Stone will continue to work fine until you close it, switch Users, or remove the mic.

In short you have to set the default speaker to LINE 1 to get the mics to appear. Then when you apply the settings switch the default speaker back.

I started getting "Error 2123" recently, and spent A LOT of time searching for the fix. Here is what finally worked:

Find the hidden file "tracking.db3". It's in the hidden folder "ProgramData/Rosetta Stone" under the "C:" directory. Copy and paste it to the Rosetta Stone install directory (Program Files/Rosetta Stone).

Error 2123 should be gone, but now there will be Error 2125. So, in the Rosetta Stone install directory, run the "service_installer" .exe file by double-clicking it.

SOURCE: I need a activation code for Rosetta Stone

What you are asking for is illegal. If you bought the boxed software then your activation code must have come in the box. If you downloaded the software, then you must have provided the email address that will be used to send you the activation code (if any).
Be it as it may, FixYa is not in the business of helping anybody break the law. There may be sites that do that, but you will have to find them on your own. Sorry.
