iTunes re-install

[BingoLittle]

I have an HP Pavilion dms-1155 running Windows 7 Home Premium.

After installing and using iTunes successfully for over a year, I was getting a couple of glitches, and it wouldn't update to iTunes 10, so I decided to re-install iTunes. I backed up, created a Restore Point, uninstalled iTunes and all Apple programs in Control Panel.

I then downloaded iTunes from apple.com (I have done it with both IE and Firefox). This throws up an error message starting "An error occurred during the installation of assembly ‘Microsoft.VC80.CRT.type=”Win32”, and another about AppleMobile Device. Although the installation finished and said it was successful, it clearly wasn't and iTunes failed to run.

So I System Restored back to my Restore Point, but now even the old version of iTunes will not run.

I have combed the forums of Apple and Microsoft and though there are references to this problem, nothing suggested there has worked. I have cleaned out every trace of iTunes and all Apple programs; I have run the iTunes set up program from as administrator from a Clean Boot: still exactly the same error messages recur. I am forced to the conclusion that the problem relates to a missing or corrupt Windows file, rather than the existence of a bad file.

It looks as if I will have to go to Recovery, which will be a real curse as I will have to restore all my programs, and find the relative installation disks and/or activation codes.

Before I do so, does anyone have any further suggestions?

Hi,

Try these commands from the RUN window:

cmd

sfc  /scannow   ----> This will verify you critical system file and attempt repairs if necessary. (note the space before the /)

Have you thought about Windows 7 service pack 1?

[BingoLittle]

Thanks. I tried that and was told I had to be an administrator running a console session to run the sfc utility.

How do I do that? I log in to Windows as an administrator, but obviously that's not good enough.

Re Windows 7 Service Pack 1 - I don't have that but do have automatic Windows Update running, and it is not being offered to me as an update. I read somewhere on the HP forum that, if one is not offered it automatically, it may be because it is not suitable for my system. Can I ignore that and install Service Pack 1 manually?

Hi,

You need to be logged on as an Administrator to do either of the above suggestions.

[BingoLittle]

I worked out that I had to right-click on the cmd icon and select Run as administrator..

Having done so, I was offered a prompt line of C:\Windows\system32> and  typed sfc /scannow (with a space before the /).

I got 'Beginning system scan' and then, after a short pause, 'Windows Resource Protection could not perform the requested operation' and back to the command  line prompt.

Any further suggestions?

And can you help me with my question about Windows 7 SP1?

[Big_Dave]

Hi,

You can download Windows 7 sp1 to your hard drive and then install it.  Be sure to backup your data in case something goes wrong.  Have you made a set of the HP Recovery Disks

I have experienced issues with the earlier versions of iTunes and basically had to do a full HP Recovery and then install iTunes.

[BingoLittle]

Nothing else worked, so in the end I had to do a full HP Recovery.

Now iTunes works once more, but what a bore a full Recovery is! Not just having to make a note of all your programs and then re-installing them all, but having to redo all the settings in each program which make life that much easier.

I think I shall do a regular system image backup in future, in case of further problems, which wil hoipefully reduce the work involved in a full Recovery.
