Error 42404 after 10.5.3.3 upgrade

Question

Has anyone got a fix for this or is it a software issue on iTunes part.  I have windows 7 64 bit and until yesterday when i did the upgrade i had no problems.  I have tried repair and uninstall and reinstall which i have done and i still get the message  " A required iTunes component is not installed. Please repair or reinstall iTunes (-42404)" it would suggest that there is something missing with the install of iTunes as iTunes worked fine up until i did the upgrade yesterday.  I have noticed a number of similiar issues here and on Google so many many people have this same problem after upgrading to 10.5.3.3

OMG!! I have fixed it ok guys here is the answer for all Windows 7 pplz upgrading to 10.5.3.3 who have the following errors:
Error 7 Windows Error 5
ItunesHelper didnt install
Itunes didnt install

error -42404
Here is the fix:
Firstly thank you to Chris, Senior Advisor at Apple he doesnt know it yet but he set me to thinking and i can now say i have solved it. Before you start make sure you have completed the unistall sequence elsewhere on the forum.
Firstly go to the c:\program files (x86) then go to Common Files now here is the trick guys you may think you have got all of C drive to show all hidden files but you may not have so click Organise, Folder Seach options and Click and click View then ensure the Show all files is selected. Now you may notice you have an Apple folder which may not have been there when you did the uninstall of the sequence listed elsewhere on this board. 
What the main issue here is if you installed iTunes but did not right click and choose install as an administrator then you will not be able to delete this folder I dont know if this is a Windows or Apple or both and why certain areas still don't show all files when you have this in C: i don't know either. 
What you need to do is right click then choose properties then go to Security then to advanced then to Owner if it says Unknown in the box you need to click edit then choose an administrator listed then click ok, ok on the next box and ok all the way back.  Now double click on the folder and click ok to the next box and you are in and you can go back and delete this folder.  Now the bad news is you have to do this to every single folder in everything in the apple folder.  This is painful but you may know of software or a trick in windows that will reset every permission in every folder under apple but i did every single one myself.  Then download fresh iTunes and Quicktime.  Right Click Quicktime and run as administrator do the same with iTunes 10.5.3.3 and your done mine is now back up and running woohoooo. Side note i did empty the recycle bin and reboot before i did the reinstall.
Cheers all
