Attempted to download itunes version 10.3.1 for 64-bit Windows Vista and get an error when trying to open itunes after a supposedly successful download. 
The error:

 

"The iTunes application could not be opened.  An unknown error occurred (-50)."

 

Apparently version 10.3.1 was supposed to fix this error.  Any ideas???

... maybe it's becoming a higher-percentage play, nowadays. (The -50 is a fairly generic time-out message, so the most common underlying causes of it tend to change over time.)

 

If your current user account is an administrative account already, it's possible you're had a permission go strange here for a file or folder or a registry key. It's always a bit tricky to tell what permission is awry with one of these, so I generally try to avoid "fixing" things for fear of mucking something else up ... So if you don't want to have to do a "Run as administrator" every time you want to launch iTunes, you could set iTunes to automatically launch as an administrator (so you can then launch it "normally" but it will do a Run as administrator).

 

To do that, right-click your iTunes.exe again, but this time select "Properties". In the compatibility tab, check the "Run as administrator" box and click OK.

Let's try a quick experiment, nikki. (It's not the highest-percentage play, but it's really quick, so I thought we'd try it next.)

 

In your Start Menu open Computer.

In Computer, open Local Disk C:\ or whichever drive you've got your program files installed on.

Open the "Program Files (x86)" folder.

Open the "ITunes" folder.

Right-click on the iTunes.exe file and select "Run as administrator".

 

Does iTunes launch then without the -50?

The error -50 apple was referring to in the update occurred when syncing, not the one you are experiencing

    "The iTunes application could not be opened.  An unknown error occurred (-50)."

     

    The -50 in that context can indicate damage to your Apple Application Support. (Apple Application Support is where single copies of program files used by multiple different Apple programs are stashed.) So I'd first try a repair install of your Apple Application Support.

     

    Restart the PC. Head into your Uninstall a program control panel, select "Apple Application Support", and click "Repair".

     

    Does the repair install go through okay? If so, does your iTunes start launching again?

    The Repair Install went ok (or at least I didn't receive an error) but the same error when opening iTunes appears.  I tried repairing iTunes as well.

    Sorry for the delay.  B Noir, that did work and launch correctly.  So is it now permanently fixed?

    I'm now able to get on and use iTunes, but have an error when trying to sync the ipod to the computer:  We had purchased some music and apps thru the ipod and had it synced to another computer until the correct computer was operational.  The error:

     

    "We could not complete your iTunes Store request.  An unknown error occurred (-9808)."

     

    I had received an error stating that the ipod was not authorized on this computer, so I followed the instruction to go to Store > Authorize This Computer.  I haven't seen this error again so believe the computer is now authorized but don't know if it's connected to the above error or not,.

  • nikkifromhuntington Level 1 Level 1

    Actually, the computer has not been authorized as I get the same (-9808) error when attempting to authorize it.
