I keep getting error 7 windows 126

Question

How can I fix this problem?

Answer 1

I Had this problem along with the error message that it's missing the driver GNSDK_DSP.DLL. I am Windows XP and fixed the error by going to Start>My Computer>Add or Remove Programs
When the Add or Remove programs list is "populated", Find iTunes on it. Click the link that says "For more information" and the iTunes box will expand.
You will see a button that says "Repair" and it says to reinstall the program if it is not working correctly, use the "Repair" button.
I clicked the Repair button and it automatically started the reinstall. When all the progress bars disappear (it didn't really give any other indication that it was done) click the "close" button and try to open iTunes again. It worked first time for me. I also saw another forum where someone said it worked for the other Windows versions by following the same route, just that in other windows versions it might be "Computer" instead of "My Computer" and the Add or Remove Programs function is also called something else.
BTW, this problem occurred after a big Windows security update.I don't know for sure that had anything to do with it. Also should mention that rebooting the puter after I first got the error messages when trying to open iTunes did no good whatsoever. And also saw posts on other forums to make sure and use the Add/Remove Programs program and not try to manually uninstall because it won't work. The "Repair" button in Add/Remove Programs did work very well.
Hope this helps somebody having this problem. It drove me crazy finding the answer, but the fix was super simple once I found out what to do.
