ITunes 9.2 Will Not Launch

Question

I'm running 64 bit Windows 7 Ultimate on a Sager/Clevo custom laptop. Every time I try to launch iTunes, it crashes. I have tried uninstalling and reinstalling iTunes but that does not work. Any help on solving this problem would be greatly appreciated. Here's the error report I get from Windows when iTunes "stops responding."

Answer 1

I downloaded iTunes for 64 bit Windows from apple's site. After the installation, when I clicked on the iTunes icon, an error message came up saying that the shortcut was only for products currently installed.
Good lord, it's fighting back hard. But at least that is giving us some further insight into what might be going on. Usually that error message indicates trouble with the iTunes64.msi on the system ... so trouble with that might well have caused issues with the update to version 9.2. (The .msi contains the installation database for the program, so damage to that can prevent old files from being swapped out for the files for the new version during an update.)
I also hadn't realised (or thought through the implications) that you were running a 64-bit operating system. So we need to tweak the instructions from that Apple document in order to make sure that we've properly cleared away all the leftover program files.
Let's try the following proceudre this time, which involves a bunch of additional explicit precautions (just in case). Best to print these instructions out, because at one stage of proceedings, you won't be able to use a web browser.
Preliminaries
(a) Download and save a fresh copy of the 64-bit iTunes installer (iTunes64Setup.exe) to your hard drive. (Don't run the install on line and don't start the install just yet.)
http://www.apple.com/itunes/download/
(b) Download and install a copy of the Windows Installer CleanUp utility from Microsoft:
http://support.microsoft.com/kb/290301
*Uninstall phase*
Proceed with the instructions from [Removing and reinstalling iTunes, QuickTime, and other software components for Windows Vista or Windows 7|http://support.apple.com/kb/HT1923] with the following amendments.
(a) If when uninstalling any of the 6 listed applications, you get an error message (especially one about a "missing msi"), run the Windows Installer CleanUp utility ("Start > All Programs > Windows Install CleanUp"). In the list of programs that appears in CleanUp, find the entry for the program that doesn't uninstall, select that entry, and click "Remove". Quit out of CleanUp and proceed with the next uninstall.
If all the programs seem to uninstall correctly, prior to moving to the *Verify iTunes and related components are completely uninstalled* section, run CleanUp anyway afterwards. Check the list of programs in CleanUp for any Apple Application Support, Apple Software Update, Apple Mobile Device Support, BonJour, iTunes and QuickTime entries. If you find any such entries, select them in CleanUp and click "Remove". Quit out of CleanUp, and proceed to the *Verify iTunes and related components are completely uninstalled* section.
(b) When you get to *step 9* of the *Verify iTunes and related components are completely uninstalled* section, instead use the following steps, rather than the ones goiven in the document. (Those ones in the document aren't quite accurate for 64-bit systems at the time that I'm writing this reply.)
(9) Right-click the Apple folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
Note: If you have a 64-bit version of the Windows OS, continue with step #10. Otherwise, skip to step #17.
(10) Open the Program Files (x86) folder.
(11) Right-click the iTunes folder (if it still exists), choose Delete, and choose Yes when asked to confirm the deletion.
(12) Right-click the iPod folder, choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
(13) Right-click the QuickTime folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
(14) Right-click the Bonjour folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
(15) Open the Common Files folder.
(16) Right-click the Apple folder (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
(17) Open Local Disk (C:) located in Computer or whichever hard disk your operating system is installed on.
(18) Open the Windows folder.
(19) For 32-bit versions of Windows: Open the System32 folder.
For 64-bit versions of Windows: Open the Syswow64 folder.
(20) Right-click the QuickTime file (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
(21) Right-click the QuickTimeVR file (if it exists), choose Delete, and choose Yes when asked to confirm the deletion. Click Continue if Windows needs confirmation or permission to continue.
(22) Right-click the Recycle Bin and choose Empty Recycle Bin.
*Reinstall phase*
Restart the PC. After the PC restarts, *do not open any applications.* Disconnect from your network and/or the internet. Now disable all your security software (firewall, antivirus, antispyware).
Now start the reinstall by doubleclicking the iTunes64Setup.exe file you downloaded earlier.
Reenable all security software prior to reconnecting to the internet and/or your network.
Did the iTunes reinstall seem to go through okay?
If so, does iTunes launch now, without the StackHash-referencing "iTunes has stopped working" messages?
