iTunes won't install (at all) on my Windows 8.1 64 bit computer

For general advice see Troubleshooting issues with iTunes for Windows updates.

The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.

Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

If you've already tried a complete uninstall and reinstall try opening iTunes in safe mode (hold down CTRL+SHIFT) as you start iTunes, then going to Edit > Preferences > Store and turing off Show iTunes in the Cloud purchases. You may find iTunes will now start normally.

Presumably at this point iTunes isn't installed. See the Further Information area of the user tip for direct links to the current iTunes installers. Download and open the 64-bit installer.

I have the same problem - downloading iTunes onto a virgin PC (never had iTunes before). The download appears to be clean, but when attempting to install, Windows pops up a warning that this app can't on this PC. Followed tips, still no luck. The issue can't be resolved by SHIFT-CLICK open of iTunes, as it is not installed.

Help!

And this isn't a Windows RT device, and you downloaded the correct 32/64 version as appropriate? Can you please download a fresh copy of the setup file using one of the two links in the Further Information area of the user tip. Right-click or ctrl-right-click on the installer to see if you can Run as Administrator. If it won't install can you please post back the exact text of any error message.

I am having this problem it wont install i have downloaded the appropriate 64 bit file for my machine and every time i try to run it (as administrator or not) it brings up the "are u sure you opened this app" i click yes the nothing at all occurs.

Try the section Install missing components to break down the iTunes installer into the individual .msi files and install one at a time. Can you install each component successfully? If not which one won't install and what error message do you get?

I'll tell you what I get. Can't install apple mobile device support. NO OTHER STATEMENT! When I try to instal it via device manager - I get info is invalid. My computer won't even recognize my new iphone. Had it in tech support for two days - no help from them. Am going to take my computer to a microsoft store and let them look at the error messages.

I had iTunes working on my Windows 8.1 machine. I copied a CD in, using iTunes, shut everything down, then when I got home, I tried to open iTunes so I could get the files moved to my phone. Rather, I tried to open 4media ipod max, since I use more than one laptop for my music needs. 4 media wouldn't open because there was an error with iTunes. So I uninstalled iTunes and deleted all folders associated with it and tried to re-install... it gives me an error saying that a dll is missing and I have to contact my network manager. Now I've uninstalled both programs and it still won't install--same dll error. I thought because they share dlls that this would help, but now I can't do anything. My hot spot doesn't work with the laptop any more, nothing apple or iTunes related will. I've tried the suggestions above, to no avail. Any thing else I could be missing that might be causing this conflict? I did download the 64-bit version for my machine.

What is the full text of the error message?

If the advice above doesn't resolve things you could try this alternate version:

iTunes 12.1.0.71 for Windows (64-bit - for older video cards) - itunes64setup.exe (2015-01-28)

which is a 64-bit installer for the 32-bit version of the core application, similar to previous 64-bit releases.

Or roll back to the previous build:

• iTunes 12.0.1.26 for Windows (32-bit) - iTunesSetup.exe (2014-10-16)
• iTunes 12.0.1.26 for Windows (64-bit) - iTunes64Setup.exe (2014-10-16)

Then try again from the top.

It didn't do anything.

Uninstall all Apple components as outlined in the second box of the user tip. then install using the method given in Install missing components.

I used 7zip and I was unable to install iTunes or apple mobile device support. It gave me the exact same error as the screenshot above.
