HT1349 Have gone to sync Itunes and program does not start up. Have uninstalled and reinstalled and still nothing. Very frustrating as it has 6 devices I maintain.

Question

Have gone to update and sync Iphones and Ipods and Itunes does not start up.

Answer 1

Both the sccbase.dll and slbcsp.dll failed giving the error "LoadLibrary("xxxxxx.dll") failed. - The specified module could not be found."
There's our likely culprits. We'd better try swapping them out on the PC.
(The instructions I'm about to give are quite possibly going to sound odd ... I'll explain what we're doing and why at the end of the post.)
Navigate to the C:\Windows\System32\ directory. (If you've set a different directory from \Windows\ as your Systemroot, look for \System32\in the alternate Systemroot rather than Windows.)
Can you see sccbase.dll and slbcsp.dll in there?
If so, drag each of them to your Desktop.
Now close the C:\Windows\System32\ window, wait about 5 seconds, and then open navigate to C:\Windows\System32\ again. Have copies of sccbase.dll and slbcsp.dll reappeared in that directory?
If one or both of the dlls aren't replaced and/or you get an error message from Windows saying you have a system file missing, move the dlls back into \System32\ from your desktop, and post back.
(What we're doing here is using XP's Windows File Protection system. It maintains a \dllcache where copies of essential dlls are kept on the PC. If it detects that a dll from \System32\ is missing, or has been replaced by an earlier version, and it has a current version of the dll in the dllcache, it will move a copy of the correct version of the dll into \System32\. There's more information about this in the following document from Microsoft: Description of the Windows File Protection feature.)
If the dlls are replaced, try restarting the PC and then relaunching iTunes again. Does it launch this time?
If it doesn't launch, try reregistering sccbase.dll and slbscp.dll again. Do they reregister properly, or do you get an error message again?
