win7 x64 can't install iTunes 10.5

I got the permissions C:86x..... error again with Apple Airport setup, try installing the program in a new folder in your C drive instead, worked for Airport like a charm. I did unistall the Apple updater also but that did not help with getting Airport to load.

Its makes me nervous to ever update anyting Apple on my PC

Hey,

I have Windows 7 64-bit and I am trying to download the iTunes 10.5.2 64-bit download. However, I am getting the error message:

An error occured during the installation of assembly ''Microsoft.vc80.crt.type=''win32'', version=''8.0.50727.6195, public key token=,1fc8b3b9a1e18e3b'', processor architecture=''x86'', please refer to help and Support for more information. HResult: 0x80070422

I ignore this message and the installation starts its "rolling back action" process. After 15 minutes of waiting, iTunes finally downloads. However, when I try to connect my iPod Touch 4G, I get a message saying:

This iPod cannot be used because the required software is not installed. Run the iTunes installer to remove iTunes, then install the 64-bit version of iTunes

I think that even though I download the 64-bit iTunes download, it still gets downloaded as the 32-bit version. I have read through many other forums on this site and have tried uninstalling iTunes and all Apple programs, but the same thing occurs. If anyone could help, I'd really appreciate it.

From your description of the symptoms, it sounds like Mobile Device Support is not installing during the iTunes upgrade, hence the roll-back. Carefully follow the instructions here: http://randomwindowstips.wordpress.com/2009/12/08/windows-7-itunes-9-software-is -not-installed/

and good luck.

I have wrestled with this problem since October and spent many hours trying every posted solution, as well as speaking with tech support and engineers at Apple, as well as Microsoft. This appears to be a common symptom with multiple possible causes, and no single solution will fix it for everyone. I have found NO workable solution (short of reinstalling Windows 7, which I'm unwilling to do just to synch my Apple products with my desktop). Apple clearly is both clueless and unconcerned about this problem.

If you use a PC with Apple products, don't expect Apple to provide useful support, and don't expect new iTunes releases to help (two have come out since this problem erupted, and neither has solved the problem). BTW, I'd bet money that no one at Apple reads this support forum...or cares. My solution is to use an old XP laptop for my Apple gadgets. Awkward, yes, but better than beating my head against a wall.

I finally did it. I did a clean install of Windows and iTunes is working fine. It was a time consuming process, but the added benefit was it cleaned up other issues as well and my computer is working like it is new. However when you consider the time spent trying to resolve the many issues a clean install actually takes less time, or at least it did for me. I hope everyone else has good luck getting the issues resolve.

You would lose the bet. I spent days with very high levels of Apple support working with them on this problem and they are neither clueless or unconcerned, and furthermore they are very aware of the comments in this forum. Your statements tell me that you believe the Apple applications are the cause of all of these problems but that is very unlikely since a clean install of Windows would not solve the problem. Just think about it. Apple has everything to gain in app, music, ring tone, and book sales when iTunes works on PCs. What does Microsoft gain? Not a **** thing. BTW, I used the work-around on page 19 of this thread to get iTunes up and running and have managed to easily incorporate the last two updates. I know it is a work-around rather than a fix and I'm not happy about that but for me, it's better than a complete reinstall of Windows.

Prove it. Prove that the hours I spent talking to Apple techs resulted in ANYTHING to fix this problem. The engineer I was referred up to had not even HEARD of the problem and could find no record of it in Apple's logs. This was weeks after it first surfaced. When I've called back, they have had no additional solutions.

As I said, many different issues seem to be at play, and no one solution works for everyone. I'm tickled that it worked for you, but nothing has worked for many others. If Apple really cared about solving this, they'd be tracking down the trouble reports and working with its customers until they identified the problems and solutions.

Living in Silicon Valley, I'm weary of people glorifying Apple. It just happens that Apple has an incompatibility problem it hasn't found a way to solve or hasn't bothered to solve, and hasn't acknowledged. When a company releases software that won't work for a segment of their customer base, it's their responsibility to fix or face the consequences.

Enough of this.

Having the same troubles. I have been trying to do this for the past 2 day, I think. I have uninstalled itunes. and it will NOT let me reinstall this comes up very often, along with the others that people have posted

Dude, you helped out a lot. Thanks for the fast response to my problem and thanks for the link to a quick solution.

Well, perhaps attitude has something to do with it. I sent an email to Tim Cook and got a response within 24 hours from Cupertino. I then worked with technicians from the Apple Support center in Houston for several days over a 2 week period. Over many hours we took a number of trace logs and tried several solutions. During our conversations there was mention of Apple activiely attempting to work with Microsoft to solve the problems.

Stating the facts instead of ranting is not glorifying Apple, it's just telling the truth instead of playing the blame game. Again, have you considered the idea that this may in fact be a Windows problem and therefore impossible for Apple to solve without cooperation from Microsoft? Just because your dealings with Apple did not result in a fix doesn't mean they are uninterested.

My own guess, after many hours of frustrating work, is that in the case where uninstall of all of the Apple software results in a fix, the problem was caused by resididual files left over from past interrupted ugrades. But in those cases that are not fixed by uninstalling all of the Apple Software, the registry is permanently hosed, and I'm not sure why. I know for a fact that my Windows registry is missing an entry and try as I might, I have not been able to repair it. Therefore, I use the work-around solution and so far, that allows me to sync my Apple devices with the latest version of iTunes.

Glad it worked for you and happy to help an Alaskan. One of my sons lives in Juneau.

YEA IT'S FIX!

REINSTALL WINDOWS WILL FIX THIS LAME "TIM COOK" problem.

Repair/reinstall/registry etc all tried no luck. I forgot spent how many hours to fix this just because I need ios5.

Tried repair windows no luck, so I backup and reinstall the whole box. End up only took me 30mins to have Win7 64bit box and itune up and running.

Oh well good luck, hope the next itune fix the problem.

I figured out a way around installing the new 10.5, you have to install 10.3.1 and then update from there once installed. Yes you will have to ignore it once but then it patches through and works. You can find 10.3.1 for windows 64 bit here....

Hope I helped anyone out

To be clear.... You are saying uninstall 10.4.2, than install 10.3.1, than upgrade to 10.5.2?

What was the specific error were you getting in your event viewer? There have been at least 4 specific issues associated with the 10.5 upgrade.

Day 3 of trying to download this stupid itunes system (the one which came with the hardwear was 32-bit) everytime I click "download" it promptly says "thank you for downloading itunes" - needless to say nothing, nada, nill, zip, not a sausage....... It started once, but the connection was poor and I had to stop it! Dell Inspiron 64-bit, this app is obviously spelt with a silent "Cr"............
