Oh Apple, I go crazy with this problem away. Quick fix this problem lightly.

Having exact same issue can anyone help!

Same issue, please help, win 7 64 bit here.

Exactly the same problem with Windows 7 x86 (32bit).

By installing Microsoft Visual C++ 2008 Service Pack 1 i get the same error message.

I extract the iTunesSetup.exe (10.5.0.142) into another directory and started the AppleApplicationSetup.msi.

The Setup runs until i get this error "hresult:0x80073712" and then the setup runs back.

Can anyone tell us, how we can fix this problem.

Microsoft's solution for this problem:

Side by side confiiguartion errors, no help from microsoft, their fixs does'nt work either.

Same here. I did manage to install iTunes 10.5 a couple days ago with no problem, but a couple of hours ago when tried upgrading my iPhone to iOS5, at the point of restoring, the iPhone driver didn't install correctly and my phone is stuck in recovery mode. I uninstalled iTunes in an attempt to re-install it and see if the driver issue is fixed, but I can't install it now because of this weird error.

Hi Don,

I saw where you posted that you were having the exact same problem as one listed previously, but you were using win7 64bit. The problem listed earlier was a person who was running 32bit. I suspect that you've simply got a 32bitcopy and not a 64bit copy. Some may aruge that a 32bit should run on a 64 i.e. forward compatiable but I've not seen too many cases where this was successful. Given that your also running software that was designed form a different operating system altogether and then 'repatched" to run in a windows envirorment I'd just look for the 64bit copy and be done with it. I saw you had nine replies to your issue but I couldn't read any of them so this may just end up as rehash. Either way good luck!

Exactly the same problems as many others with iTunes 10.5 and my Windows 7 32 bit laptop: An error occurred during the installation of assembly 'Microsoft.VC80.CRT .type="win32", … HRESULT:0x800736FD. I followed the Apple instructions to completely uninstall earlier iTunes and all Apple applications and then tried to re-install iTunes 10.5. Numerous attempts. Still no success. Constantly goes through the install and then rolls back after failure.

By unzipping using WinRAR and installing each module separately it seems that the module that fails is the AppleApplicationSupport.msi

Finally I uninstalled everything again and reinstalled iTunes 10.4.1. This installed perfectly. So at least I still have iTunes.

I was able to install iTunes 10.5 on myWindows XP SP3 desktop.

I noticed with WinRAR that the AppleApplicationSupport.msi file with 10.5 is a completely different size to that with 10.4.1. This suggests to me a conflict between the latest AppleApplicationSupport.msi and Windows 7.

I have this same issue...hurry up APPLE!

Same issue here, on AMD 64 Bit Win 7

Have the same problem.

I tried all options to remove/reinstall-zero Result.

I have the same problem. I tried the hole day!! I think there is a problem with the windows update: MS Visual C++ 2008 SP1 (KB2538243). I can't install it en it stay in my windows update...

I think when i solve this problem also the iTunes problem is solved.
