Itunes wont open on my computer

I am not absolutely certain that i have understood you.

When you click on iTunes, do you see the hourglass briefly, but iTunes does not open and there is no error message?
If so open your taks manager after trying to open iTunes and look on the processes tab. Can you see iTunes.exe there although iTunes does not open?

If so you have a particular type of launch failure that is often associated with problems with cryptographic services.

Did you make any changes to your system before the problem started?


If it happened out of the blue, you need to run a scan for malware. It might also be worth a second opinion from an online scan but ONLY use a big name, such as Kapersky or similar. There are many scams out there that introduce malware.

You need to be sure your system is clean before starting troubleshooting as malware can not only cause this problem but also interfere with a solution.

Once you have done that, here is a method for diagnosing the problem, you need to report back with the results and then we can look at a solution.

Troubleshooting silent launch failure in Windows XP

Before checking if iTunes works, restart your PC or close the iTunes.exe process with task manager if it is running.

A couple of simple things to try:

Stop the bonjour service, this FAQ has instructions:
http://support.apple.com/kb/HT2250?viewlocale=en_US


But usually it is due to a problem with cryptographic services.

Check to see if you have your smart card service and that it is not set to disabled. For some reason iTunes needs it.

Start>>Run>>Services.msc
you should find the smart card service in the list. Report back with your findings.

Malware can interfere with cryptographic services and also prevent a resolution so it is important to check that your system is clean before proceeding: Run a virus and spyware scan with up to date definitions.


Then work through *Method 4* in the following link:
http://support.microsoft.com/kb/822798

You should be able to copy and paste the individual lines to save on typing.

Make a careful note of any error messages you get, they are important for diagnosis. Report back any error messages especially the names of any dlls mentioned.

If there are no errors try starting iTunes.

I have this same problem. Recently had memory upgrade done. Tried all troubleshooting steps. Nothin. Started smart card service. Nothing. Worked through method 4. Got this message after typing both slbcsp.dll entries: "Load Library ("slbcsp.dll")failed. The specified procedure could not be found." Can you help?

For morwynn06 only:

It appears that slbcsp.dll is missing from your system32 folder.
You need to obtain the file, if you have another XP computer available copy it from C:\Windows\system32.
Otherwise dlls can be downloaded from here:
http://www.dlldump.com/

The site appears to be reliable as far as I can tell, quite a few forum people have used it.

Copy the file into c:\Windows\system32
Then do the method 4 thing just for slbcsp.dll. I am not certain that this is essential, but it is a good idea to make sure it is registered.

Did it. Tried the method 4 thing and got the same message. itunes still won't open.

I have this problem too. It shows in the processes but doesn't open. I've tried all of those methods and was unsuccessful. No firewall or malware either. Come on Apple! Step up!

The method I gave is diagnostic not a solution.

You have to have to say what happened when you did the various steps with any errors in full. Then it may be possible to say what you have to do to resolve it.

Unfortunately Apple does not give good help on this particular problem. Perhaps because it is a complex issue that may have several causes.

You have not given me anything to go on.

Did you do what I said in my post? You should not get a "not found" error message when you do method 4 if you copied the missing dll into you system32 folder.

You might want to use Windows Explorer to check if slbcsp.dll is actually in your system32 folder.

Hello, I get that error message "iTunes error 13005". I have my itunes database on an ext HD, I completed an update yesterday from Apple and my itunes wont open on my computer, giving me the above error message. I have read the resolutions offerred in the thread but I not been successfull in solving the problem. I have deleted the Genius and extras files, rebooted the computer and still the same message.
Any further advice?
Thanks
Chris

You need to start your own thread. It is not good to post on a thread when your problem is not identical to the original problem. It gets too confusing to deal with different issues in the same thread.
There are already three people on this thread.

Find the Using iTunes for Windows forum: http://discussions.apple.com/forum.jspa?forumID=800
You will see "post new Topic" on the top left.

Polydorus, Oops, sorry about that, I'll try to start my own thread.

Cheers

Sorry - I copied the missing .dll into the system 32 folder. Used Windows Explorer to check, and it is there. However, I am still getting the same "not found" message when I do the method 4 thing.

That is very odd.
Just to double check, you are using XP as in your signature.
You only get the not found error for slbcsp.dll, all the other dlls are OK.

.
I don't understand that if slbcsp.dll is in the system32 folder and you typed in the command correctly. You can use copy and paste on a line from method 4 to be sure there are no typos.
What is the full text of the error message again?

Yes, I have XP (service pack 3 if that matters). Yes, slbcsp.dll is the only one that I get the error message for. The message is : "Load Library ("slbcsp.dll")failed. The specified procedure could not be found." The only thing that is different from when iTunes was opening, is the memory upgrade I had done.

OK, I think I am going to have to duck out here.

I do not understand why you are getting a not found message if you typed the regsvr32 command correctly and the dll is in your system32 folder and all the other dlls worked OK.

Do you have anyone locally who knows about computers and could take a look at this. Maybe they could work out what is happening. It is the kind of thing where I wish I could sit at your PC and see for myself.


Or maybe someone else on the forum has a suggestion.

AS far as I know this dll must be present and registered in order for iTunes to work. It attempts to open slbcsp.dll during it's start up.

Thanks for your help anyway,polydorus. Since I am having so much trouble with that .dll, it's got to be the problem. Maybe someone else will come on who knows how to fix this.
