Reinstalling iTunes

Ran into a huge issue with iTunes not starting and crashing out with an offset error in iTunes.exe. Tried multiple reinstalls of 7.2 and all failed. Finally performed the following:

• Uninstalled Itunes
• Uninstalled Quicktime
• Searched for 'Apple' on the hard drive: deleted all programs
• Searched for 'iTunes' on the hard drive: deleted all programs
• Searched for 'Quicktime' on the hard drive: deleted all programs
• Open the registry: removed all Apple registry hives
• Ran CCLeaner on the registry
• Went to OldApps.com and downloaded the following versions of iTunes:
  • 4.1, 4.8, 6.05
• Installed 4.1 (no reboot)
• Ran 4.1
• Quicktime not installed
• Installed current Quicktime
• Ran 4.1
• Installed 4.8 (no reboot)
• Ran 4.8
• Installed 6.05 (no reboot & iPod support)
• Ran 6.05
• Installed 7.02 (downloaded three weeks ago)
• Ran 7.02
• Agreed to program update

Updating my podcast feeds now. I may need to consider tweaking the Synch program to work with iTunes.
