Q: whem installing itunes i get this message "this installation package could not be opened. Verifiy that the package exists and that you can access it, or contact the application vendor to verify that this is a valid windows installer package"

Try repair your Apple Software Update.

Go to START/ALL PROGRAMS/Apple Software Update. If it offers you a newer version of Apple Software Update, do it but Deselect any other software offered at the same time. Once done, try another iTunes install

If you don't see ASU from ALL PROGRAMS, check from your CONTROL PANEL

START/CONTROL PANEL/PROGRAMS N FEATURES/highlight APPLE SOFTWARE UPDATE and click REPAIR button.

Temporary disable your firewall and security software.

Check your windows 7 whether it is a 32bit or 64bit and download the right iTunes version. (START/ right mouse click COMPUTER and select PROPERTIES)

Download iTunes from here:http://www.apple.com/itunes/download/

Donot install, choose save file first.  Then install.

Let's check your Windows system.

1.  Have you done all the important windows updates and service Packs on your system.  If not do it now.  START button, type in Windows Update and ENTER.  Select 'CHECK FOR UPDATES'

2.  Let's check your Windows system files for possible file corruption

SCAN and repair possible Windows system file corruption:

Go to command prompt (START/ALL PROGRAMS/ACCESSORIES right mouse click "command prompt" and choose "Run as Administrator"

type in

sfc /scannow

let Windows fix any system files that need to be repaired.

Restart the computer if it did actually repair any files.

3.  Check your system for possible Malware.  But you have to do it in WIndows Safe Mode.

Start your computer in "Safe mode with networking", go to this link download a free version of Malwarebyte.

http://www.malwarebytes.org/products/malwarebytes_free

Install and perform update immediately, then do a full SCAN. Remove malware if it indeed finds any. Restart computer to regular windows to let Malwarebyte complete the removal.

To start your computer in safe mode

Press and hold the F8 key as your computer starts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you'll need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.

On the Advanced Boot Options screen, use the arrow keys to highlight the "safe mode with networking" option, and then press Enter. Log on to your computer with a user account that has administrator rights.

When your computer is in safe mode, you'll see the words Safe Mode in the corners of your screen. To exit safe mode, restart your computer and let Windows start normally.

If you have saved the installer file, instead of double click to execute the file, can you right mouse click the file and select "Run as administrator"?

The same thing is happening to me and i don't understand why.

I had the same problem but i realised that it wouldnt install because my laptop was using a 32-bit operating system and it says when you try to download it you need a 64-bit operation system.

I have the same problem. IS there a solution or i have to forget about apple products? thanks

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 the page in case one of them applies.

The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with third party software.

Your library and device backups should be unaffected by these steps but there are links to backup and recovery advice should it be needed.
