Invalid Signature MSG Installing Itunes 11.4 - Windows 7

When will Apple fix the "INVALID SIGNATURE on the install of Itues 11.4 for a windows 7 pc ?
I have seen this post several times.
Apple does not always admit they have software issues.

Hi black3793,
Welcome to the Apple Support Communities!
I know it can be both frustrating and concerning when iTunes becomes unresponsive when you connect your iPod. In your situation I would start by isolating iTunes by uninstalling it and all of its components in the correct order and installing fresh. Please follow the steps in the attached article for removing iTunes and its components.
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
Remove iTunes and related components from the Control Panel
Use the Control Panel to uninstall iTunes and related software components in the following order and then restart your computer:
iTunes
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support (iTunes 9 or later)
Important: Uninstalling these components in a different order, or only uninstalling some of these components may have unintended affects.
Have a great day,
Joe

How do I install iTunes with a Windows 7 account that uses parental controls?

I have setup a small computer for my daughter to use, running Windows 7 Home Premium. I've enabled Parental Controls through the control panel. So far, I've been unable to install iTunes for her. If I try running the installer as admin, when I try to run iTunes as her, I eventually get a message telling me that itunes64.msi was rejected by the digital signature policy. If I run the installer as her, I get a message saying the system administrator doesn't allow the app to run; I have added the installer to the list of allowed applications. Anyone know how to install iTunes in this case?

what can be wrong?

I recommend you do as LexSchellings and I are telling you to do. If you have uninstalled iTunes and the reinstalled it from Apple's website and it still does not work, you will have to contact the Apple Technical Support section for them to guide you through steps to try and get it working.

I cannot install itunes on my windows vista

I try to install itunes on my windows vista, it gives me a error

"iTunesSetup.exe não é um aplicativo Win32 válido"
That suggests that the installer is getting damaged during the download.
I'd first try downloading an installer from the Apple website using a different web browser:
http://www.apple.com/itunes/download/
If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

Install ITunes on A Windows 7 64 bit and get error message

I am trying to install ITunes on A Windows 7 64bit and get the following error microsoft.vc80.crt,version="8.0.50727.4053",type="win32",publickeytoken="1fc8b3 b9a1e18e3b",processorarchitecture="x86"HRESULT:0x8007054F

Are you using the 32 or 64 bit version? There are two versions of iTunes. One is for 64 bit processor architecture, one is for 32 bit processor architecture.
Please download the 64 bit version and test it! In my view you try to install the 32 bit version.
Kind regards!
Philipp
EDIT: I am sure you currently try to install the 32 bit version! It doesn't work on a 64 bit system. Are you sure that you use Windows with 64 bit?

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.

CAN'T INSTALL ITUNES 9 ON WINDOWS VISTA 64-BIT OS

Hey guys!
I'm having a reaaaallly hard time installing iTunes on my Windows Vista 64-bit OS. Everytime I think it's about to finish installing, it shows me this message:
What does it mean?? Can someone PLEASE help me, I haven't had music on my iPhone for 4 weeks now!

Curses ... you did everything right by providing the screenshot, thanks. But we really need to see the error message number that shows up after the "HRESULT" bit for one of those, and it's deciding not show us that.
Okay ... people who get these error messages for iTunes installs typically are also getting Windows updates failures too. So we'll try to work out what the iTunes/Updates issue is by checking your Update history.
Go into your Windows Update and click "Update History". Have updates been failing for you recently? If so, doubleclick on each failure to bring up a small window showing some info about the failure.
What error message codes are you getting for the Windows Updates failures? (For example, 0x8007000B, or something else?)

The section Install missing components has advice on breaking down the iTunes installer into the individual .msi files which might prove useful if AAS won't install normally.

Just installed itunes on new windows 7 system Cant get it to import cd's when it is open. I have to close it first and then insert cd to import

If your library was working on your computer and then popped up empty all of a sudden then this might be what you need...
Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

I cant install Itunes on my windows 8 laptop. (unspecified errors encountered)

I have tried to install Itunes and Icloud on my windows 8 laptop. I have hunted all through the laptop and see no sign that any apple product has ever been on this laptop, yet iget errors during the install process that causes the installer to abort the install and go right to finish. I have tried to install Itunes repeatedly and it always fails at the same point. Icloud also fails to install. I get a message that says errors have been encountered, but no indication of what those errors are. can anyone suggest a fix for this? or tell me what it is I am doing wrong?
