Went to install the latest iTunes (with Quicktime) and got a nasty looking iDriver.exe -- Application Error message.
Opps, I’ve seen that before. It’s part of the install shield tool and not iTunes. Here’s what to do about it:
1) Disable your Anti-Virus system during the duration of the install.
2) Open Task Manager and kill all the processes starting with iDriver, iTunes, and iPod, including the helpers.
3) Re-run the iTunesSetup.exe program again.
If you get an error message at this point, go to this page on Trouble installing iPod, iTunes, or QuickTime software in Windows.
