When trying to download Itunes this pops up " key not valid for use in specified state" what does this mean and how can I fix it?

When trying to download Itunes this pops up " key not valid for use in specified state" what does this mean and how can I fix it? I am using a pc laptop if that makes any difference.

Try reading through this thread: key not valid for use in specified state. Possible solution involves moving the RSA folder. Rather than deleting it as aniwack suggested I'd try this:
For "Key not valid for use in specified state" errors try moving the folder RSA from C:\Users\<User>\AppData\Roaming\Microsoft\Crypto\RSA to say C:\RSA (just in case there should be a need to restore it) then try installing again. This folder appears to act as a cache and should be rebuilt automatically as required.

I note this information from Wikipedia: "DVD Studio Pro was a high-end software tool published by Apple Inc. to allow users to create DVD masters to be sent out for replication at production houses. Its tight integration with other Apple applications allows users to take Final Cut Pro and Motion projects and render them into the DVD format without encoding to intermediary formats. This streamlines the production workflow and reduces overhead."
If that is your intent, finding a substitute program that will run on your Mac may not be as efficient. Others can advise you on alternatives, or you can post a new thread specifically with that question.
BTW: what Mac and what version of OS X?
If it is important to you to continue to use DVD Studio Pro, consider the option of installing Snow Leopard (with Rosetta) into Parallels on your Mac:

Tried updating to 11.4 Itunes and it says "key not valid for use in specified state"

when I tried to update ITunes to 11.4 I get an error message saying " key not valid for use in specified state" I tried uninstalling iTunes and downloading the new version but it still won't download. I also tried syncing my Iphone 6 and it wouldn't let me until I updated to 11.4 which brings me back to my problem???

"key not valid for use in specified state" when installing itunes

I recently uninstalled an older version of itunes, and every time i try to install the newest version it wont work.
I just keep getting the message "key not valid for use in specified state". If you know what to do could you
please make it simple. also do not send me to apple's help section, it does not have ANY answers.
thanks.

There is a link to 7-zip in the Install missing components section of the user tip Troubleshooting issues with iTunes for Windows updates, but if you have the key not valid error the advice above should work, and there is no need to break down the setup file.

ERROR: "key not valid for use in specified state" when updating to Lightroom 5.6 in Win8.1

While doing a routine update from Lightroom 5.5 to v5.6 in Win 8.1, the installation halted at the start of the installation with the vague error message, "key not valid for use in specified state". Although v5.5 was working just fine, the install routine deleted the v5.5 application files. I rolled back to the previous system restore point (set just prior to the install) and recovered the executable files. However, now the 5.5 files won't open the default catalog, none of the backups, or even create a new catalog.
As v5.x was purchased as an update to v4.x, I've tried to reinstall the original Lightroom v4.x app from the factory disk. I get the same error.
Suggestions?
Thanks. Dan

I have a similar problem to Dan. while doing a routine upgrade from Lightroom 5.5 to 5.6 I got the
: "key not valid for use in specified state"
error and now Lightroom has completely disappeared. I've tried to uninstall, but there is nothing to uninstall. Going back to try to install the original 5.4 just results in the same error.
A problem may have been that I closed Lightroom when the upgrade started to download. It then re-opened again when the install was halfway through., I assumed that was an error and closed it. just after that the error first appeared in the installer.
I still had an older version of lightroom 4 installed. I've uninstalled it, and that didn't make any difference.
I've also tried removing anything in the registry left over from the old installs and that didn't help either.
Any suggestions?

Issue installing ITunes : error key not valid for use in specified state

On the latest update for iTunes for Windows the updated couldn't complete as it gave me the following message " key not valid for use in specified state". I then completly uninstalled iTunes and its components in the order advised, rebooted my system, ran the latest ITunes setup and still get the message " key not valid for use in specified state".
I have checked all the directories to ensure no remnants.
Any one got an answer to this issue as I no longer have access to ITunes. I have a Laptop running Windows Vista Business
Thanks,

It seems we may have a more targeted solution. Based on posts in the thread key not valid for use in specified state I've just added the following to the user tip.
For "Key not valid for use in specified state" errors try moving the folder RSA from C:\Users\<User>\AppData\Roaming\Microsoft\Crypto\RSA to say C:\RSA (just in case there should be a need to restore it) then try installing again. This folder appears to act as a cache and should be rebuilt automatically as required.

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.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

It's a really bad idea to post your iPhone's serial number and I've asked the Hosts to remove it.
Any one device can create only three iCloud accounts. As you have apparently already created three accounts (or if it's a used phone the previous owner did) you cannot create any more one it. This is tied to the hardware, not the account, and there is no way round it.
You can create a new iCloud account on another iOS device or on a Mac, and then you will be able to sign into that on your iPhone.

That error is caused by a Windows Update. Make sure you have all subsequent updates installed.
