Just found a fix for a problem that's been driving me nuts for a month.
A few weeks ago, sometime in early September, I tried to go to the iTunes store and found myself locked out of my iTunes account. Anything I tried to do that involved a transaction of any kind resulted in an alert dialog that said: "iTunes could not connect to the iTunes Store. An unknown error occurred (-9812)." That's it. No diagnostic information, no tips, no links, no help whatsoever. A less useful dialog box, I cannot begin to imagine.
Apple's site was of no use whatsoever. The troubleshooting advice I found there was incredibly lame. And of course, the -9812 error code means exactly what the dialog says it means: Unknown Error.
I figured there must be someone, on one of the forums, who would have found the answer to this problem. I did a lot of searching (and wading through a lot of lame "did you try this? did you try that?" non-answers), to no avail.
Finally, on September 18, Mike P. Ryan posted what (for me) turned out to be the solution, on discussions.apple.com.
The problem? A corrupt or missing trusted root certificate for iTunes. How or why this got messed up on my Vista machine, I don't know, but the same thing has clearly happened to boatloads of people, judging from the uproar on the discussion boards. The cure is to download Microsoft's latest trusted root certificate update from here: http://www.microsoft.com/downloads/details.aspx?FamilyID=f814ec0e-ee7e-435e-99f8-20b44d4531b0&displaylang=en. Follow the wizard instructions carefully, because you need to download two executables, not just one.
Note that the fix works for Win XP as well as Vista.
Mike, if you're reading this, thanks!
downloaded both exe's and the latest version of itunes, installed, restarted and all to no avail.. someone needs to figure this one out (hint hint apple - make yur shit work)
ReplyDeleteI had this issue, this ended up being the fix, thanks for doing the leg work on this one.
ReplyDeleteThanks a lot. I have been working on for this for about 2 weeks for a friend. I did some of the leg work to looking through all the forums and found nothing that worked. This worked for me. Thanks again.
ReplyDeleteThank you thank you thank you. This fixed it. Well done
ReplyDeleteHELL YEAH! It worked!
ReplyDeleteDownloaded rootsup.exe and WGAPluginInstall.exe, installed, and it work, thanks a million!
ReplyDeleteThanks for sharing nice infromation. I have really needed it. I am suffering with same problem since few weeks.
ReplyDeletethanks for posting this - tried for weeks to find a fix for a girl I'm dating: getting laid thanks to you!
ReplyDeleteWas on the phone with Apple tech support and was told that it was my fire wall. 1 hr later, the rep still couldn't help. Thank you for your help! I downlaoded the certificate and can once again buy music!
ReplyDeleteThis worked for me!!!
ReplyDeleteThank you! I have a thread on this on the apple forums and you are correct they are no help. Apple "support" is useless. They actually told me to tell Microsoft that THEIR program wasn't working. They didn't even tell me what the error was that I should tell Microsoft.
this worked ! OHMYGOD thank you!
ReplyDeleteit worked, just like you said! Thanks for through the malarkey and posting the fix. Apple should send you some royalties for one-upping their incredibly-convoluted help page on this topic. Thanks again!
ReplyDeleteWell! i am on mac os and i have this problem anyone can help?
ReplyDeleteThank you so much for that. I have been tearing my hair out for weeks making all sorts of changes to firewalls and hosts. One quick download (well, two like you said) and it is all sorted. You are an angel. :-)
ReplyDeleteAT LAST...IT WORKS!!!
ReplyDeleteAbsolutley brilliant. I've tried so many things - Apple are clueless (or unwilling) - A thousand thankyou's. :)
Ok.... seriously... its been 6 months I've been having this problem when hitting the "Get" or "subscribe" button to a podcast. (All purchases were fine). I install the two darn things... and even without re-booting OR RESTARTING ITUNES OR RESEARCHING FOR THE PODCAST... IT WORKS!!!!!!!!!!
ReplyDeleteYou are FANTASTIC !!!!!!! IT WORKS. Thank You
ReplyDeleteUnfortunately, this didn't work for me, however, removing the iTunesPrefs.xml file located in C:\Documents and Settings\yourUser\Application Data\Apple Computer\iTunes did work. Per this post:

ReplyDeleteFO-shitzelll my mutha FN-nizzal that totally worked yeah!!... thnx
ReplyDeleteTried everything from computer restart, itunes restart, router restart, modem restart, firewall settings, several suggested changes on internet options, DLL files.
ReplyDeleteThis finally fixed the problem.
This didn't help me because I keep getting an error message that I can't bloody validate. Which I don't understand cause unless the Microsoft store in freaking Redmond WA is selling counterfeit junk then I'm up the proverbial creek.
ReplyDeleteI keep getting error code 0x80072efd. Aaaarrgghhh
I had this problem after updating my touch to software ver 4. I could access the store from my computer but my Ipod only showed Itunes symbol and cable. Your solution fixed the problem thanks for your assistance.
ReplyDeleteHad this problem - followed instructions as requested. Worked first time! Genius. Thanks for saving so much of my time trying to get to the bottom of this.
ReplyDeleteWorked for me! Thanks for the tip!!
ReplyDeleteLEGEND!!!!!!!!!!!
ReplyDeleteDownloaded v4 for my iPod Touch and got the error, but found your directions to the fix. It worked. Thank you much!
ReplyDeleteDoes this fix only apply to people using Windows Firewall, as I have Norton Security?
ReplyDeletethis articale is very help full for me when i got iTunes -9812 error on my Mac. this articale having very good information about the error 9812. after fix the iTunes error it also help to clean my mac.
ReplyDeleteThere is a reason why I bought a Mac, it was not to be one of the cool kids that wanted the best of the best. No it was because of the music production I do on it. Hours and hours sitting in front of my Mac copying, pasting, moving, deleting, hour after hour just beating on my Mac in a endless assault to get my work done. That is the key part, my work. I work from home, it is great, but even if it is from home it is still work and it still needs to get done. So my Mac, I have it because it is fast, gets the job done and comes back for more.
ReplyDeleteBut what happens when it doesn't want to do those things anymore?
I move around massive amounts of information and yes even on the almighty Mac this can cause a problem after a while. Things fragment, programs get corrupted issues come up. My light speed Mac slows down to a crawl and all of the sudden I simply can not get any work done. Because I work from home there is no IT guy to call and ask to come fix it. No instead I have to figure out what is wrong. I am lucky, I did, but not after trying everything under the sun first and wasting countless hours looking for one program that can do what I needed instead of ten programs. One program to lead them all….okay that was a lame Lord of the rings reference, but that program was/is Detox My Mac. A simple to use program that did not just fix my issues, it put my Mac on overdrive again. A few clicks and my Mac was clean and ready to rock and roll again.

For some trainers or proprietors, switching Best Dog Harness over to a dog harness may seem like DogHarnessGuide a separation from a relied on approach.
