Error 1635: This Update Package Could Not Be Opened

Recently I've been getting an Adobe Update Failed error popping up in my task bar:
I've tried the Microsoft FixIt listed as a solution for this error on the following page, but it made no difference: http://helpx.adobe.com/acrobat/kb/update-errors-acrobat-reader-windows.html
I'm running Windows 7 Ultimate x64. I've tried fully unstalling and reinstalling Adobe Reader and periodically I still get the same error.
The weird thing is though that I'm running v11.0.0.4, isn't this the latest?...
I've allowed Adobe Reader and Adobe Update through my Norton Internet Security firewall too. I've tried researching this error but the only thing I can find is old threads with broken links, or support details for Adobe Reader 8.

Thanks, weird as it still shows v11.0.0.4 being the latest on the main Adobe page?
http://get.adobe.com/uk/reader/
Anyways cheers, that file installed with no problems. I opened Reader and clicked the Repair Installation option too for good measure.
Will see what happens next time an update is available.

Error message, this patch package could not be opened

I have been unable to use the Adobe reader for sometime but I now really need it. I have tried updating, reloading, removing to reinstall but at every move I continually get the message above and I cannot get around it no matter what I try. I cannot even remove the program from the list as this same message keeps popping up and I cannot proceed. I need help!!! The original package that came with the computer was version 7 current is 11 but it has never worked and I am unable to continue the install due to the above message also cannot delete, I have deleted all adobe keys in the registry even that does not help....

Assuming that you are on Windows
download and run the Acrobat Cleaner Tool from http://labs.adobe.com/downloads/acrobatcleaner.html

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?

What has this to do with the application Front Row which this forum covers?

At what point in the process are you getting this message? Have you tried downloading a fresh copy of the iTunes setup file from http://www.apple.com/itunes/download/ ?
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.

So i download java and then when its installing it says this: "This installation package could not be opened.

I have tryed ALOT of sulotions, downloading offline version, disaling firewall, auto protect norton, UAC, downloading other wersions of java but nothing works!!!! im getting tired of these error messages and i need a proper solution now!

So i download java and then when its installing it saysThis is kind of an obvious suggestion, but are you sure you downloaded the correct 64bit version for Windows? Check if you need the x86_64 version or the IA 64 bit version.

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.
