itunes error on windows xp

Hi, Thanks for your response. I tried to launch Quicktime and your right I get the same error message.I tried that the other day and I thought it did open. Also today I went into install/uninstall and clicked on change for itunes thinking that maybe it was not installed corectly. I got a message saying Find itunes installation package 'itunes.msi' in a folder from which you can install the product itunes. I searched for that and then clicked on it and it said to first run setup.exe. I searhed for that and 11 different folders showed up and I tried to open all of them and kept getting an error message.
I did not know if any of this information would help. But no quicktime is not working either. Thanks again.

No, I have never even heard of any of those.
Thanks for looking into this, I have no clue what could of happened.
I will wait to hear from you.

Hi, sorry to say I got the same error message on itunes and quicktime after I did all the steps in the post. I was not able to unistall quicktime through install/unistall from the control panel. I was able to delete it once I downloaded Windows Installer Cleanup Utility. Then I went and found program files, and deleted
the itunes and quicktime folders. I was not able to locate Quicktime and Quicktime VR in C;\windows\system32\folder to delete them.
Then I did the rest and same thing.
Thanks again for your help. I really do not know what to do now.

So here goes. I clicked on Quicktime in the control panel and it opened. So I clicked on each tab, they all opened except for file type. I got an error message.

Rundll:

an exception occurred while trying to run
"C:WINDOWS\system32\shell32.dll,control_RunDLL"C:\PROGRAMFILES\quicktime\QTsyste m
\Quicktime.cpl",Quicktime"

I hope that is right. Some words capitalized, some not.

Also I get another error message when I restart my computer. I do not know if it's related to the itunes, quicktime problem or not.

This says:

Error 126
Provide bca (not sure if bca is right, I cannot read my writing)
unable to load license key
license key invalid
validation library
Then I click ok
next window says
license key recorded on system is

welt-xcccxx-xcgrh-rkliy
Please check that this key matches the key you received when you ordered this product
it also says in the box on the top right side computer associates.
I do not think they are affiliated with itunes/quicktime
I copied that down about 3 weeks ago, I hope I wrote it correctly if not and you think they are related, I will restart and write it down again
But I do not remembering purchasing anything from quicktime or itunes except for songs. Maybe they are not even related. The issue on restart happened before the itunes problem. Let me know what you think.
Just wondering do you think I will ever be able to install itunes at all. All my music is in my music file in my documents so if I lost it, I should have all of them. I just wonder how I could ever add different songs, I don't think there is any other way to use an ipod without itunes.

Thanks again for your time, I really appreciate it. I really don't know what else to do.
What is the time difference? When I finished this reply the time here is:
11:55 pm, Tuesday 10/27.
Just curious.

Wow 19 hours ahead of us. That's crazy. Most of you are probably heading home after work and it's not even Wednesday here.
Sorry off subject.
I never go on websites or anything and write to people, so I don't really think about timezones.
I just find it interesting.

Hi,
Thanks for helping.
I believe I am the only user as far as the computer thinks. When I put the computer in standby, then go to use it again my name is the only one listed. Other people do use the computer and have email accounts but I bought the computer.
I will check out what you sent to read, in a few hours or so, then send feedback.
Thanks again.

Hello,
Just added the new account, itunes and quicktime still will not open.
Any other suggestions.
Thanks Again
