Apple Application Support is required to run iTunes.

Happy to help!

This method worked for me. Thank you for posting! Tried the WinRAR method and somehow downloaded a bunch of spywear! Then I had to go through the hassle of removing the spyware. Your solution of dowloading the old version of itunes was much easier anyway. I have another computer I can't open itunes on, so once I remove itunes and all related programs and reinstall intunes, if I get the Apple Application Support error, I will use your solution without wasting hours of time.

"Run as adminstrator" worked for me, and it's so so simple. Thanks.

this will help:

WinRAR is not really free. You get it free if you buy some other product that they are associated with.

This is not how to deal with the problem. I had the same problem and I went directly to Apple support. They solved me problem. It was pretty simple when I had the help of Apple support. All the advice you see on this forum isn't always correct.

Again, For Windows users. Uninstall iTunes. When you go to reinstall iTunes right click on the installer and choose "Run as Administrator". That will solve the issue. If you don't have admin rights it not going to work.

how can I download the winrap ?? plz help me

Perfect!!! Dont understand why this worked but it did!! I was ready to give up!! Tried just about everything!

BTW: the "VC80.crt" problem is caused because a specific version of the Visual C++ 2005 CRT dlls is missing, namely 8.0.50727.6195.

I actually found this thread when I encountered the problem on Windows 10. Fortunately I have a solution as well 🙂.

Version 8.0.50727.6195 is not included in "Microsoft Visual C++ 2005 Redistributable Package (x64)" or in the SP1 version,

but in "Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package MFC Security Update":

Install that & iTunes should work.

Hope that helps

In my case, running the install as Administrator produced the same error. Problem persists.

Clean Windows 7 system with all updates installed.

How is it possible that a company like Apple produces so ****** installers???

Great solution. Thank you very much!

This worked for me so I can open and use iTunes again so thank you very much 🙂

But - iTunes still does not see my iPhone or my iPad. The message is that the requested software is not installed. What do I do now to correct this problem?

Thanks

With iTunes closed try the following:

1. Open Control Panel > Device Manager
2. Plug in your device
3. Locate Universal Serial Bus Controllers > Apple Mobile Device USB Driver
4. Right-click and select Update Driver Software...
5. Click Browse my computer for driver software
6. Browse to C:\Program Files\Common Files\Apple\Mobile Device Support\Drivers or
   C:\Program Files (x86)\Common Files\Apple\Mobile Device Support\Drivers
7. Click Let me pick from a list of device drivers on my computer
8. Click Apple Mobile Device USB Driver
9. Click Next, then Close and exit Device Manager
