"MSVCR80.dll Missing"

iTunes no longer starts on my PC the message is: this program cannot start "MSVCR80.dll Missing". This program has operated well for months and I have made no alterations other than attempting to install the latest update, what should I do?

Windows 7

Never had a problem updating iTunes - until tonight. I received the same messages as others: MSVCR80.dll not found; iTunes was not installed correctly Please reinstall iTunes Error 7 (Windows Error 126). I tried reinstalling as well as fixing with a reinstall - all to no avail. I am not comfortable with removing everything and trying for a new installation. For that matter, why should I. Apple needs to address this widespread problem!

g.50cab.

Amen to that. How could they send something out like this that screws up everybody with Windows 7...which, to date, is still Microsoft's top OS for PC's.


Apple...you guys out there? Anybody listening? Are you working on an updated update?


My system was working perfectly until that little iTunes update prompt came along Sunday night.


Thanks Apple....

BeachNanny,, you asked

" if we downloaded the latest version of iTunes and now it works, what was in the update to make it not work?"


My assumption is that the problem was not in the update itself but was due to a faulty former installation of the Apple Mobile Device Support driver. Many of us noticed that that one could not gracefully uninstall anymore. The update procedure does notice that and abort before completing, leaving iTunes in an incoherent state. The full uninstall allow to switch in a different install behavior that reestablish everything.

It looks as though your Library file has been lost. I had this problem the other day and realised I should have backed it up. When this happens iTunes creates itself a new Library file which only contains stuff you purchased from iTunes.


In your iTunes folder you should find an old version of this file (in the folder "Previous iTunes Libraries") and you can rename your 'duff' Library file (iTunes Library.itl) to something like "iTunes Library corrupt.itl", copy or move an old Library file (eg.iTunes Library 2013-11-21.itl), into the folder where your corrupt file was found, rename it "iTunes Library,itl" and all should be well! You will then just need to add in your more recent purchases to your Library.


Because all the songs are in a separate Media folder (usually "iTunes Media"), they will still be available once you've restored your Library.
