I recently tried to upgrade my itunes on my dell laptop with 64 bit windows 7. It stopped working so I deleted all files and tried to reinstall and haven't been able to since. I've tried numerous things i've read in forums and nothing seems to work. The installation will not move past the "publishing product information" point. After being stuck there for a while this error message appears:

An error occurred during the installation of assembly 'Microsoft.VC80.CRT,version="8.0.50727.4053",type="win32",publicKeyToken="1fc8b 3b9a1e18e3b",process or Architecture="x86"', Please refer to Help and Support for more information. HRESULT: 0x800736FD

I hope someone is able to help me with this.

Did you already try what bnoir suggested in this post about error 0x800736FD:

These ones are typically caused by underlying problems on the PC that also often cause Windows Updates to fail to install. If we can fix the Windows Update trouble, we can usually get the iTunes trouble cleaned up en passant.

Go into your Windows update and try to check for new updates. If updates install, stock up on the ones you're behind on, restarting the PC if requested to do so. After the restart, try installing iTunes again. Does it go through this time for you?

If windows updates fail to install, go into your Update History and doubleclick the failures. What alphanumeric codes appear for you? Are they also 800736FD, or some other number? (If they're another number, what number are you getting?

This thread might help as well, suggestion provided by bnoir:

In general, these ones tend to be caused by underlying problems on the PC that can prevent Windows Updates from installing. So my main strategy with them is to try to fix the Windows Update issues. If we can get Windows Updates flowing again, that generally clears up the iTunes install errors +en passant.+

Head into your Windows Update, and check for any new updates. Do any fail? If so, open your Update History and doubleclick on the failure entries to bring up a small box with alphanumeric error message codes. Are you getting 8000FFFFs? (They often seem to be associated with an iTunes-install 0x800736FD.)

If you're getting 8000FFFFs, try the following Microsoft document:

[Windows Update Error 8000FFFF|http://windows.microsoft.com/en-US/windows-vista/Windows-Update-Error- 8000FFFF]

Head back to Windows Update, and stock up on any updates you're behind on. Once you're completely up to date in that regard, try another iTunes install. Does it go through properly this time?
