First off, very disappointed that it's a major PITA to install a Razer Megalodon on a Windows 7 machine. If you've found this post, you're probably in the same boat as I was. You may have found the Razer support page which claims to fix the problem, but clicking on the firmware update link at the bottom of the page leads to a 404. You may even have tried the Youtube video to follow along, but noticed the comment from @cultofrazer that says "We've removed the file as we are currently developing a new firmware updater for the Razer Megalodon. We anticipate the updater to be released toward the end of February."

Well it's mid-April and there still isn't an update from Razer. However, I successfully installed the Razer Megalodon on my Windows 7 machine using the following process:

1. Download the 2.12 firmware update; Razer keeps on deleting the file from their website and I keep on finding other locations. Let me know if the previous link leads to a 404 and I'll find a new one.
2. Plug in the headset to a USB port, go to Control Panel -> System and click device manager. Open up Sound, video and game controllers, select Razer Megalodon, and uninstall
3. Unplug the headset and run the 2.12 firmware update executable.
4. Next, and this is important, plug the headset into an obscure USB port that you'll never use again. Windows will install the driver.
5. Unplug the headset and plug it into the USB port you will always use; make sure you always plug the headset into this port, otherwise you may have problems and need to go through the process again.
6. Finally, go to Control Panel -> Sounds and you'll see "Speakers 4-Razer Megalodon". Click the device and select "Set Default Device".

Hope this helps, let me know if it works for you!
