QuickTime 7.7.8 no longer installs on Windows 10

RIP QuickTime for Windows. Apple is "deprecating support" for the application, and will no longer patch security flaws in the software.

In this regard, QuickTime for Windows now joins Microsoft Windows XP and Oracle Java 6 as software that is no longer being updated to fix vulnerabilities, and subject to ever-increasing risk as more and more unpatched vulnerabilities are found affecting it.

So, Windows users should uninstall Quicktime. How to do so is detailed here:

https://support.apple.com/en-us/HT205771

Mac OS users should not do so as the security risks that have prompted this do not affect the Apple OS.

I'm receiving the exact same error, and the weird thing is i already have quicktime player on my other Windows 10 desktop, but the error is occurring on my Windows 10 laptop which i upgraded to 10 a while back when windows 10 first came out.

Please help me install QuickTime Player on my laptop!

It's probably still showing QuickTime 7.7.6 because Apple didn't update their webpage. QT 7.7.7 came as an update and is working with Windows 10, where did you see QT version 7.7.8? The best I could tell is 7.7.7 is the latest version for Windows.

OK good link, it is showing QuickTime 7.7.8. I'll try and run it and see what I come up with on Windows 10

Getting the same message when trying to run that installer with Windows 10. So apparently there's not an installer for Windows 10? I installed Windows 10 on top of QuickTime 7.7.7 so that is working, and not familiar enough yet with 10 to know if Apple has an installer for 10 or will?

I have the same problem, not being able to upgrade to version 7.7.8 from 7.7.7.

I cannot uninstall version 7.7.7 as well. I get this error message

The text is in Danish and says something like this: An unexpected error has occured during installation of this package. It can indicate, that there is a problem with this package. The error code is 2229.

I'm using Windows 10, which has been upgraded from 7 -> 8 -> 8.1 -> 10

Same problem and messages for me (german user)! Whats wrong by apple??

Based on Apple's website the installer for QuickTime 7.7.8 is for Windows - Vista or Windows 7 only. So Apple right now doesn't have a QuickTime installer for Windows 10. I upgraded a Windows 7 computer to Windows 10 without reformatting the hard drive. Because Microsoft sent me Windows 10 online. The Windows 7 computer already had QuickTime 7.7.7 installed when I upgraded to Windows 10, and QT is working fine, so it's compatible with Windows 10.

I don't know if Apple will have a installer for Windows 10, where browsers seem to be doing away with plug-ins or so they say. I've seen online where some websites are showing a QT installer for Windows 10. That would be risky getting a QT installer not from Apple, you don't know what's included in the installer.

Same issue here - I use Patch My PC Updater software and it keeps warning me that my Quicktime is not current (7.77 installed, 7.78 available). But like you when I go to the Quicktime update page & download the update, I then get a message that the 7.78 is only for Windows 7 / Vista users. Perplexed and hoping someone from Apple clues us Windows 10 users in soon .....

Same issue with Secunia - complaining that I am on 7.77 and 7.78 is available.

Apple needs to fix this.

A solution that works was posted at http://tommynation.com/install-quicktime-windows-10/ . Option 2 is needed for 7.7.8. Essentially he modified the check in the install package to accept windows 10.

I downloaded this installer and seems that it has a vulnerability (Exploit.gen).

This is the reason I recommended his alternate 2 (for me alternate 1 didn't work). Download the official 7.7.8 from APPLE. Unzip it apply using the msinstaller and his small fix file.

I downloaded TommyNations custom installer and it failed as well, so I"m giving up for now
