"The iTunes Library file cannot be saved. There is not enough memory available."

Well I dont get the problem everytime, iTunes should not have a 64bit version to download if it does not properly support it, most 32bit applications work fine on W7 when using a 32bit installer

I get the problem everytime iTunes start now and I agree it shouldn't have a 64-bit version of itself if it's not done but Apple bundles some other software that's compiled as 64-bit software however iTunes itself is not.

The problem however will remain until a 64-bit version of iTunes exist because 64-bit applications can address more memory than 32-bit applications.

I find myself moving to another application at this point. Without advertising too much the app is made by J River. My database consists of 495000 songs at this point and iTunes doesn't hold up at all.

Bye Apple. Fix your stuff. Thanks.

No reason that itunes can't be fully 64bit. It's about 1/2 64bit and 1/2 32 bit on Win x64 systems and FULLY 64bit on OSX... itunes also DOES NOT use multiple CPUs. It make have various other services which each can use a cpu thread... but at the heart, iTunes is not a multi threaded app on Windows OR OsX.. this is a huge problem.. it's one of the reasons why it's such a HORRIBLE program for video playback 1) it only uses 1 cpu thread, 2) it does NOT use the GPU to decode video... VLC and Windows media player and Divx are FAR better ways to play something back... but if it's a video bought in the iTunes store, you MUST use iTunes or an iphone/ipad.

If me and my partner did not have 2 iphone 5ses and 2 ipad 4s, I'd have dumped itunes ages ago (We've actually both had even 3rd gen click wheel ipods before touch devices).. Hence why we've kept iTunes for so long.

I get that Apple wants people to go 100% mobile, but the fact is people , many people, still use desktop and laptop for video playback

That memory error is erroneous.. it's still happening on the most recent version.. it happens if there's still tons of disk space and plenty of memory .. and iTunes doesn't ever approad the 2GB max of memory that a 32bit windows app can use... and the Itunes exe IS a 64bit executable for Win x64 systems giving iTunes virtually unlimited memory it can use..

I just checked the box "don't warn me"... issue gone.. I ignore it... my computer backs up nightly.. and if the library gets corrupted, I restore from backup.. and it RARELY gets corrupted.. hence why I just ignore that error. It says it can't be saved, but yet it's STILL saving properly - at least for me.

Apple really needs to get their head out of their *bleep*, and FIX itunes.. it wouldn't take much work to:

1) Make ALL components 64bit

2) Multi threaded to use 2-4 CPUs

3) use ATI or nVidia cards to decode video data

I got this message aslo. I download The Gotherfather trilogy, then this starts. Also The Godfather screen flashes black after 15 minutes or so. It fixes it to restart Itunes, but only for 15 minutes. I have not yet made a purchase from Itunes that did not have some problem. I regret using their servises.

I have this very same problem too only i have like 240TB of free space to fill so go figure.

I think every body does regret using/buying there products and services, I know i am starting to. I have since built a new PC for my self. its Kool I'm so glad i did.
