I tried updating to the newest version of iTunes & it started, but then I got the error message that the program didn’t install correctly and then another error message saying
program can’t start because MSVCR80.dll is missing from your computer.
The solution from Apple support says to:
- go to program files for iTunes & look for .dll files.
- If you find QTMovie.DLL, or any other .dll files, move them to the desktop.
- Reboot computer.
- Then it says to uninstall and then reinstall iTunes.
What are .DLL files and what do I do with the ones I move to the desktop per the instructions?
Also, when I reinstall iTunes, do I have to authorize my laptop for iTunes again? If yes, doesn’t that use up one of the authorized computer uses allowed by Apple?
