Q: App Store's blank page - final solution

No actually, this bug happened once I updated. I wasn't having a bit of trouble until I updated.

Just use the solution in the original post. I was having the exact same problems but this fixed it.

Here's the fix:

There is simple solution for that case (forWindows 7, 64):

1. C:\ProgramData\Apple\Installer Cache\AppleApplicationSupport 2.0.1

2. Right click

3. Uninstall

4. C:\ProgramData\Apple\Installer Cache\AppleApplicationSupport 1.5.2

5. Right click

6. Install

7. Restart Windows

I'd try it and see. It worked for me and I'm running Windows 7 64 bit. Try it.

I am another one who upgraded to the latest and had the iTunes blank screen problem unitl I followed these instructions.  I also could not backup or sync anything until implementing this solution.

Fantastic Jerry, cheers!

JerryFromKrakow - THANK YOU!!!!!!! The thought of having to spend yet another hour or so uninstalling as previously suggested frustrated me to no end.  This 5 minute solution is working PERFECTLY!!!  Computer is running, access to store and my Ipad backs up. 

Thanks Again!

@globalist:  I have the latest version. It doesn't fix it.

Er, I think you mean it didn't fix it for you?

I would like to thank veryone for all there help. I finally decided to trash all of the Apple files on my hard drive and reinstalled itunes 10 for Windows XP etc. Everything is working fine now. Once again Thank you one and all.

Still not fixed this for my daughter and she is getting very frustrated that she can't access the iTunes store. Please can someone give me some suggestions. We just keep getting "The system administrator has set policies to prevent this installation" every time we try to uninstall anything to do with iTunes. Does anyone have a simple solution please ( other than stop using iTunes!!!!)?

Windows Vista Home

This solution works for the previous version of iTunes, but not for iTunes 10.5 (at least for me). I get error messages when I try to open iTunes 10.5 after uninstalling AppleApplicationSupport 2.0.1 and reinstalling 1.5.2.

The problem with 10.5 is that it is not compatible with Apple Application Support versions that are earlier than 2.1.5 so these solutions will not work with the previous version of 1.5.2.  Do not install this earlier version if you have already downloaded 10.5 as you create more problems for yourself.

The new 10.5 also locks up when it starts and tries to go to the iStore. Task manager says is is not responding; I have to kill it with task manager. what a POS! Windows 7, 64bit.

Figured out my issue!

Background:

Win 7 64 bit

Itunes 10.5 public release

Iphone 4

Symptoms:

Iphone 4 backup/sync hanging

Itunes Store was blank

Fix:

Uninstalled AVG Family Safety (like net nanny, an online website monitoring app for my children)

ran command promt as administrator, typed netsh winsock reset

Rebooted

That fixed boy my backup and itunes store issue.  My suggestion is if you have anything like this, Norton Online Security, Net Nanny, AVG Family Safety, Safe Eyes, Covenant Eyes, etc. you should start by uninstalling it and see if it fixes your problems.  Hope this helps someone.

try this:

Start --> Programs --> Accessories (Right Click on Command Prompt) --> Run as Administrator

then type in:

netsh winsock reset

After this restart - it worked for me perfectly

got it from another thread:

Thanks to Xeta!!!

That worked for me also! Using Windows 7 64-bit with Quicktime & iTunes 10.5

Lots of THX!!!
