Internal Failure - Error Number 0x80040707

Hi there! Thats a common error message. Try this and see if it works:
1. Run the setup program and PAY ATTENTION to the folder where you are installing the software. Keep clicking on the "Next" button and here it is, the progress bar.

2. When the progress bar reaches 100% and you get the 0x80040707 error message, DO NOT click "Accept" or "Ok" or whatever says the button in the error window. Instead proceed as I describe:

3. Go to the the folder where the program is supposed to be installed. Yes, it's there!. Copy this folder to another location (for example, to the desktop).

4. Now click "Accept" or "Ok" in the 0x80040707 error window. This will erase almost every file in the folder where the program was originally installed. Who cares? You have a copy of it.

5. Now overwrite this almost-empty original installation folder with the one you backuped.

6. If you want you can even create manually a shortcut of the EXE file that launches the software wherever you like. Double click it. Does it work?

iTunes generally goes into MyDocuments under MyMusic

Hi Rachyl,
I recently posted a message about the fact the new iTunes installation wiped out FIRST my iTunes folder....and then my whole one-tear old MAxtor SATA drive became unreadable.
However, the message is nowhere to be seen although it was there after I posted it. Have any idea what might have happened to my post and MORE importantly why did the new iTunes installation wreak havoc wiping out almost 200G of music!!!! 😟 Thanks!

It should not have wiped out your music. It is most likely there, we just need to locate it. Sometimes funky things happen with updates. I had that happend to me with the update to version 5, but I was able to find my music.

When you say your SATA drive is unreadable, what exactly is going on and which Windows OS are you using?
