ITunes "encountered a problem and needs to close" error

Question

hey guys and gals, i really need help. i've been trying to fix my iTunes software for months now. Without further ado, here's what happened:
installed itunes
deleted quicktime accidently
installed quicktime
installed itunes
itunes still doesn't work
installed and reinstalled multiple times from both the c.d. and itunes.com
Therefore, when i attempt to open my itunes program, the dialoge box stating, "iTunes has encountered a problem and needs to close. We are sorry for the inconvenience. Send error report, dont send."
the details of the error report are:
"information regarding the condition of iTunes when the problem occured; the operating system version and computer hardware in use; your digital product id, which could be used to identify your license; and internet protocol(ip) address of your computer.
we do not intentionally collect your files, name, address, email address or any other form of personally identifiable information. however, the error report could contain coustomer- specific information such as data from open files. while this information could potentially be used to determine your idenity, if present, it will not be used. the data that we collected will only be used to fix the problem. if more information is available, we will tell you when you report the problem. this error report will be sent using a secure connection to a database with limited access and will not be used for marketing purposes."
for the love of god, help me. i really wanna get my itunes working.(i have no antivirus software, such as mcaffee or norton, etc)
i really appreciate it

great, but when i did this, the agreement popped up and disappeared as soon as it came up, before i could press anything.
yuck. that's consistent with a malware infestation problem that has been causing error-less itunes launch failures since late October. but there's another couple of main possibilities that we have to check on for these "error-less" launch failures. let's try to firm up the diagnosis a bit.
first let's make an observation.
reboot your PC. open Task Manager to the Processes Tab. now try to launch itunes again.
does an itunes.exe process appear in Task Manager? if so, does it persist in there, or disappear after a few seconds?
if itunes.exe persists in Task Manager
do you have Norton Internet Security 2005? if so, first see:
iTunes 6 won't open on a Windows computer if firewall software is not up-to-date
... but if no joy with that, try the trusty Lorraine M technique:
Lorraine M: NIS/itunes problem rectified
... but if you don't have NIS 2005 (or symptoms persist), check up on this possibility:
iTunes for Windows doesn't open after upgrading
if itunes.exe doesn't appear in Task Manager (or disappears after a few seconds)
then we have to check up on the malware possibilities.
(this is not a cure, it's a final diagnostic.) use MSCONFIG to get iTunes launching again:
Using MSCONFIG to troubleshoot conflicts in Windows
after the selective startups, don't launchother applications prior to opening itunes. (this has been known to re-trigger the launch suppression.)
post back with a list of the Startup items that you needed to disable in order for itunes to launch again. exact spelling and capitalisation please.
