Itunes update failed. MSVCR80.dll is missing

The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.

The error would appear to be some kind of clash between the current installer and previously installed components that, apparently randomly, affects some users but not others. Once the older components have been removed as described the latest version of iTunes installs properly.

Thanks. This worked.

I also did a system restore on both my laptops (windows 7 and windows vista) to a point on 1/23 and 1/22. Computers restroed fine, have all my files, but I did NOT update I-tunes when propted. Will wait for a fix from Apple (for a little while) before doing the complete program removal, etc. as Turingtest2 and others have suggested.

It finally worked!!! Thanks for your help.

I do have one other question regarding HD space. In my 3 previous attempts to install, uninstall, reinstall, etc..., everytime I installed it, it would take up about 1GB of HD. However, when I successfully uninstalled and reinstalled, no HD space was freed up. Any ideas how I can find these files to free up some HD? Thanks again for your guidance as I was so lost without it.

This didn't work for me, gave a message that the task was running even though services gave the option to 'Start'.

Workaround I found was to open Task Manger and 'End Process' on the apsdaemon.exe file.

After stopping this, was uble to uninstall Apple Mobile Device Support.

I saw comments that this is one bug and that we should all just move on. In the past three months I've had various iOS updates delete all of my data from my iPhone 7 separate times. Had to troll through these forums to find work arounds. I've been told by years by fanboys that Apple products are so much more reliable than MS. That has definitely been my experience to date.

This will be my last apple product. Such a poor experience and no conern or visible attempts to iron out all bugs prior to release.

Just to add that the solution by turingtest2 did it for me without deleting my library, playlists, or unchecking/checking any songs.

One of the programs would not uninstall, but it worked just the same.

Thanks!

I really need help, my whole library is gone with lastest update iTunes 11.1.4!!! Tried to restore to 1/21/14 and still nothing. If I unistall and reinstall will that help and will all my music come back? I can't even back up at this point.

I had this problem too. Uninstalled itunes. Rebooted my computer. And downloaded itunes from the website

ok I finally got all restored!!! Went and found previous version 11.1.3 and all came back!!! Found version FileHippo.com

The lastest version *****!!!

turingtest2 - I have itunes ..4 installed, but not Apple Mobile Device. Couldn't get it out and can't get it back in.

Please help.

Hi I've got the same problem. When uninstalling everything did you also get rid of the iCloud installer as well?

Cheers

You shouldn't need to uninstall iCloud. I don't think it will hurt if you do.

Thanks to all who recommended uninstall/reinstall. It took ten minutes. It now works perfectly.

It's a Duh, I'm afraid. Killed security (eset), control panel, programs, ADM, repair. Service is running, set to automatic.

Thanks for your patience. This gets *so* frustrating - life drains away thru one's fingers. Looks as tho as much is back to as close to normal as it ever needs to be - until I trash this faithful old beast and buy a quiet little macmini with ssd. Sleep, perchance not to dream :O)

Hope things resolve themselves satisfactorily for you guys in the end. Cheers.
