ITunes installed - will not open

Question

I am experiencing the same problem as a majority of users on this post. iTunes worked without a hitch until I installed Version 6 two weeks ago. Now, I can install iTunes and it allows me to complete the install. However, when I go to open iTunes, I receive the error message window:
"iTunes has encountered a problem and needs to close.
We are sorry for the inconvenience. Please tell
Microsoft about this problem." I have the option
to "Send Error Report" or "Don't Send."
I have followed every helpful tip that has been posted over the past two weeks to no avail. These include:
- uninstalled iTunes and downloaded and installed iTunes
and Quicktime individually;
- turned off Anit-Virus software (McAfee) and
uninstalled, dowloaded and re-installed iTunes and
Quicktime together and separately;
- run MSCONFIG and tried operating only with qttask and
iTunes helper checked;
- run MSCONFIG and tried operating with only iTunes
helper checked;
- run MSCONFIG and tried operating with iTunes helper
NOT checked;
- run McAfee and SpyBot repeatedly;
- run EWIDO virus/adware/Malware scan;
- and all combinations of the above-listed actions.
None of these have worked. I am at a loss for what to do next. Obviously there are many iPod users out here who are experiencing the same exact issues.
Several posts indicate that calling Apple does no good.
Someone please help - my patience level is beyond shot.

hmmmm...what a headache,eh? I want to try a few things in your case. First, I want you to uninstall the iTunes. If you need to run the Microsoft Installer CleanUp Utility to get all the remnants out. Somewhere along the line something in the install is all kinked up, so to speak.
I dont know if you tried this, but...
. Make sure you have that file called "mapi32.dll" found in your Windows/system 32 folder.
If you cant find it let me know, I can guide you through it.
Next, make sure All these are started: TCP/IP NetBIOS Helper, Windows Management Instrument, and WMI Performance Adapter.
How to do this: Click on the Start Menu;Right Click on my computer and then choose manage in that menu. In the left hand panel click "services and applications" and double click services. Find those files and then click them and see if they say started and automatic
Next, download the standalone Version of Quicktime, with your antivirus stuff turned off.
Then Restart and download your iTunes with the antivirus turned off. Then restart and it should work.
Also, I would try a program called CCleaner which will clean out your registry. Its a free program. It seems like many are having iTunes issues due to registry problems. I would download that first before proceeding to the other steps. Make sure you let CCleaner back up your registry before you proceed, that way, if there is an error and the system becomes unstable, your registry is backed up. Let me know if this helps in any way.
