HT5318 cannot open itunes on windows 7 64 bit

I am no longer able to open iTunes on windows 7 64 bit. Have tried "repair" option and remove and redownload.

I am trying to understand the exact sequence of events here:
Firstly the iTunes installer includes Quicktime and you should not have to install it separately.
You downloaded the 32 bit iTunes installer: iTunesSetup.exe.
Normally the correct version should be downloaded automatically so that shouldn't have happened.
When you tried to run it, did it warn you that you had the wrong version and stop without installing anything?
Then you downloaded iTunes64Setup.exe
What happened when you tried to run that, did you get any error messages? If so give the full text.
What iTunes related programs do you actually have installed, if any?
Check in Programs on the Control Panel.
The following link on uninstalling iTunes lists the programs you need to look for.

Cannot open iTunes on Windows 7

I was getting an error when I tried to open iTunes that said "iTunes has stopped working" and it asked me if I wanted to send the problem to Microsoft. The error appeared after about a minute after clicking to try to open it.
I am running Windows 7, and have never before had a problem with iTunes. The only thing I have tried is reinstalling iTunes - I just downloaded the latest version and installed it (didn't delete the old one first). The result is that now I don't even get an error message, just nothing, when I try to open iTunes.
Please help!

Hi and welcome..
Might be a good idea to check the hard disk.

Cannot open Itunes in Windows 7

Itunes was running fine. I then tried to install quicktime v. 7, it would not install. But I found an earlier version 6, installed it and Itunes would simply not open, no error messages, nothing. I tried to uninstall quicktime, could not find it listed, I manually deleted the folder. Itunes still would not open. I have uninstalled Itunes and reinstalled and it still will not open. Just nothing.
Pls Help!

ps, When I 1st installed my new pc, i downloaded itunes and it worked perfectly, then update appeared , after updating, haven't been able to open since.

Cannot install itunes on windows v8.1 64 bit

Cannot install iTunes on Windows v8.1 64 bit.

The old blue iTunes worked fine on my pc, then along came the new red iTunes, which initially refused to install from an auto-update notification, saying it didn't have permission to access one of its own folders (self access to all its other folders was ok).
I then tried a manual download and install as suggested by the auto-update failure dialogue and that was exactly the same - failed at the last hurdle and had to reset itself.
I then tried download and install from iTunes site and this installed without problem, but the application will not open, neither from the desktop icon with user or admin rights, nor from a direct open or run as admin from the iTunes folder .exe file.
I have tried a repair install and an aggressive uninstall to ensure any TSR components are purged followed by a clean install - no difference.
My other pc is no problem and iTunes installed and runs on there fine, so it must be a configuration problem on this pc only.
I disabled my antivirus and malware detection during the install and made an exception for iTunes, to no effect.
When selecting the app I get a blue circle for a few seconds then nothing, no dialogue or notification of problems.
Any suggestions welcomed.

Please!
Thanks!

If anyone is reading this still looking for what caused the issue and how to fix it here is what I discovered.
The antivirus program our company uses, Bitdefender Antivirus Plus, was causing some of the PDF files not to open. After troubleshooting the different modules and settings the culprit was..
Scan SSL in Privacy Control Settings. Turning it OFF solved the problem and all the PDF files that previously would not open now open just fine. This issue has been sent to Bitdefender for them to review. If you use a different antivirus program and are having this issue try locating the Scan SSL setting and see if turning it off solves the problem.

When itunes updated it self I got error message saying Error 7 Windows error 126. I cannot open itunes. Any ideas?

I got this When I last updated itunes. Can some please help? I cannot open itunes and it is anoying!!!

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

I downloaded the latest version of itunes. Now I cannot open iTunes. I receive this error message: The procedure entry point AVCFAssetCreateWithByteStreamAndOptions could not be located in the dynamic link library AVfoundationCF.dll. Thoughts?

I downloaded the latest version of iTunes on my PC. Now I cannot open iTunes. I receive the following error message: "The procedure entry point AVCFAssetCreateWithByteStreamAndOptions could not be located in the dynamic link library AVfoundationCF.dll" After pressing the "OK" button I receive a second error message: 'iTunes not installed correctly. Please reinstall iTunes. Error 7 (Windows error 127)". I've uninstalled iTunes and reinstalled to no avail. I've also eliminated the temp files (per suggestions on the trouble-shooting page) and no luck. I also tried system restore and that did not fix the problem. Any thougths on a repair?

Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
Let's try something relatively simple first. Restart the PC. Head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (Although the procedure is for Vista and 7 and you've got XP, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)

Can't Open iTunes, installer window appears asking to restart the computer

I have windows Vista-64 bit and I downloaded iTunes 8.0.2. Now once I install the software and use it the first time, it works fine. But after first time whenever I try to open iTunes it takes to the installer window which says "please wait while iTunes configure" and then I get the message "You must restart your system for the configuration changes made to iTunes to take effect. Click Yes to restart now or No if you plan to restart later". If I restart my computer and try to iTunes again, I am again taken to this installer window and the same messages appear. Thus I cannot open Itunes. Unless I uninstall it, and then reinstall it. Then I use it only the first time after installation. But as soon as I exit, i would face the same problem again. Please help

I don't know anything about 64 bit systems and there are differences in the registry. However this problem seems to be due to a problem writing to certain registry keys due to permission issues. HKEYCLASSESROOT\.pcast seems to crop up. this post may help you:
http://discussions.apple.com/message.jspa?messageID=5489263#5489263
But if you use the the event viewer to look at error messages after the problem has occurred you may find the the problem registry key.
If you are running iTunes from a limited user account, temporarily promoting the account might work.
Sometimes you can work round this issue by creating a short cut directly from iTunes.exe. Go to Program Files\iTunes and try starting iTunes.exe. If it opens OK, right click on iTunes.exe and select Send to>>Desktop(Create shortcut). Then use this to open iTunes. It does not fix the underlying problem which is that auto repair is being triggered as the install did not complete fully.
