ITunes 10.5.2 will not open on Windows 7. No error message. Reinstall did nothing.

Question

I have been browsing the forums and looking to solutions but I have found nothing that fixed the issue. I reinstalled. I did the command prompt -> windows reset thingy. I tried modifying some kind of daemon.exe file. I don't exactly remember. In any case, whenever I try to open iTunes, my cpu usage goes up a bit but nothing else happens. QuickTime works fine however. I'm not sure what else to do. Should I just wait for a new version of iTunes to be released and hope for the best?
Any help would be greatly apprecaited.

Answer 1

Your Security, net-monitoring or video accelerator may be interferring.
If you are still having these type of problems after trying the winsock reset and are running any kind of net monitoring software like Bsecure, Net Nanny, AVG Family Safety, Safe Eyes, Covenant Eyes, Norton Online Security etc... I would suggest that you try uninstalling said software and reinstalling iTunes 10.5 to see if that corrects the issue.
Refer to article TS4123. Follow the step to identify which software in your system is the culprit and uninstall it.

Resolution
Look for modifications to Windows by:
Running MSINFO32 by choosing either Start > Run, or using the search box to search for
Once it is open, expand Components and then expand Network.
Click Protocol. The first value should look like this:
However, if you find a value that is more like this, it indicates that there's an LSP (Layered Service Provider) monitoring your computer:
"<LSP Info>" is variable and may specifically mention a software suite, or appear to be a meaningless acronym
Scroll through the list on the right and look for any LSPs that have been installed by third-party software. By default, the Windows OS will have 10 values:
MSAFD Tcpip [TCP/IP]
MSAFD Tcpip [UDP/IP]
RSVP UDP Service Provider
RSVP TCP Service Provider
MSAFD NetBIOS [\Device\NetBT_Tcpip...
The value above repeated 5 times with additional variables at the end
Note:811259.Once you've identified the third-party LSPs, determine which software placed them there. Here is a partial list of LSPs you might run into and the software that may have placed it there:
Product or Manufacturer
LSP Name
Bigfoot Networks
BfLLR over [MSAFD Tcpip [TCP/IPv6]]
ByteMobile, Inc.
BMI over [MSAFD Tcpip [TCP/IP]]
Covenant Eyes
Covenant Eyes Monitoring over [MSAFD Tcpip [TCP/IP]]
PC Tools / Spyware Doctor

SafeEyes
Internet Content Filter over [MSAFD Tcpip [TCP/IP]]
SpeedBit Video Accelerator
SBLSP over [MSAFD Tcpip [TCP/IP]]

VMCI sockets DGRAM
Once you've identified the third-party software that installed the LSP, you can remove that software. If the software is your security software, see iTunes: Troubleshooting security software issues for additional information.
Note:locate vendor information
Reset the WinSock key
If you are unable to identify the software that installed the LSP, you are unable to remove this software because it performs an important function for you, or you've removed this software and the issue persists, you may wish to reset the WinSock key.
To do so, please do the following in an administrator user:
Windows Vista and Windows 7:
Windows XP:Enter the following command:
netsh winsock reset
Restart the computer and test the issue.
Note: If the issue returns, third-party software may be reinserting the LSP.
