Upgraded iTunes in Dec, hasn't worked since (no problems previously). Won't even start in safe mode.
I've tried all the usual suspects (uninstalled and reinstall both iTunes and Quicktime, deleted SC files, removed all iTune references from Registry etc).
The iTunes appears in Processes for 2 sec only.
Any help appreciated.
Solved problem by creating new iTunes library, see:
under User-specific Troubleshooting.
I dont know what the problem was or why this worked, but it did.
