Apple application support was not found

We'll try a "standalone" installation of Apple Application Support, Geek. (It may not install, but at least we'll have a better idea of what the problem is, based on any error messages we might get.)

Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:

http://www.apple.com/itunes/download/

Download and install the free trial version of WinRAR:

http://www.rarlab.com/

Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").

Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.

Does it install properly for you? If so, does iTunes launch properly now?

If instead you get an error message during the install, let us know what it says. (Precise text, please.)

Thank You for this post!! It totally saved my Itunes and Playlist---
Reminder to self* Do not go "removal happy" on my programs.. no matter how slow I think my computer is!

These ones are typically caused by underlying problems on the PC that also often cause Windows Updates to fail to install. If we can fix the Windows Update trouble, we can usually get the iTunes/Apple-Application-Support trouble cleaned up +en passant.+

Go into your Windows update and try to check for new updates. Do they fail to install? If so, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you? (For example, "8007000b".)

i did the same thing with my computer.
i removed apple application support in order to hopefully speed it up but now my iTunes isn't working and it seem that yours was doin the same thing. plzz help me because i don't see what part of this thread helped you so could you tell me how to fix this i am desperate
thankyou 😀

🙂 Excellent news. Glad you got things working again, and many thanks for posting back to let us know about your resolution.

Here is my situation.

Trying to migrate from old XP system to Windows 7 on a new PC.

Itunes and quicktime were installed on the old pc and may still be installed; I see files to that effect. But I cannot activate Itunes or QT on the old PC.

I have ITunes on the new PC, but I haven't been able to put any of my music files from the old PC into ITunes folders. I can see them on the new hard drive, but they don't transfer via Itunes to new ITunes folders.

At some point, I got a message that told me that I already had 5 PCs authorized (I presume, to my Apple or ITunes account. That is surprising as I and my wife have only 4 PC including the new one, and one iPhone...so how could I have 5 PCs authorized already? I guess I have no way to identify the 5 "authorized" PCs.

Anyway, I tried to deauthorize the old PC (to get under the 5 PC limit) but of course, I could not because now, after converting the old XP PC to Windows 7, Itunes isn't working. When I try to install Itunes on the old PC (now, a Win 7 PC), I get a message that tells me Quicktime didn't install correctly and and Itunes needs QuickTime. This has become too complicated and obscure for me to sort out. My problem sounds vaguely like some of the problems here, but not exactly the same.

Any ideas or suggested solutions? Thanks in advance.

I was getting the error message "apple application support was not found".
After installing the AAS, I got rid of this message But Itunes still doesn't open. I'm not getting any error messages this time, just nothing happens when I double click the Itunes icon.
What should I do?

i did my anti virus Avast disable to check itunes support but cant go through got same message of error again where i am still having a problem of failure in new updates
