I'm having the same issue. Just upgraded to CS6 from CS5. Files that were able to be packaged in CS5 are no longer able to be packaged in CS6.

I'm running on a mac, running 10.7.4, and another mac also running 10.7.4.

This is a fairly serious issue as I am regularly sending files to the printer, and can no longer use the package function.

I litterally had to copy my entire font library onto a flash drive and manually bring over all the images and and links to it as well, just to meet a deadline.

So far I can't seem to find a work around.

Any help would be greatly appreciated.

Hi SmartGraphicArt and Peter Spier,

I am a Danish woman, living in Italy and having a small publishing firm. I make all our books as to graphic design etc. I have EXACTLY the same problem as SmartGraphicArt, Peter, and have been spending enormously much time on that problem. You see, our youngest book of 330 pages should have been sent to the printer yesterday, but due to a total crashdown of my computer and the taking over of a new (and thus shifting from 32 bit to 64 bit and from Windows Vista Business to Windows 7) computer two days ago. I had to reinstall all programs. I chose few months ago to take a year's subscription of Creative Cloud in order also to make a number of home pages. And now the interesting thing comes as to this problem:

On my old computer (32 bit and Vista Business) few days ago I had NO problems with the downloaded CS6 InDesign as to Garamond Premiere Pro - which is so unfortunate to be the all dominant font in the 330 pages big - and illustrated book. No problems at all. BUT in my new computer (64 bit and Windows 7) a number of fonts is missing, or some variants of these (maybe no semibold etc.), and above all Garamond Premiere Pro. My whole book is now one big chaos (of course I only work with styles, but also those are in many variants, altough built on each other). Well, I thought it had something to do with my downloading, so I redownloaded it 3 times more in all - and the result is unfortunately the same. Then I tried to see if I could get hold of the font  as cheap as possible, but that is not so simple if you want a rather big number of variants and the typography of the book is based nearly entirely on that font family.

I think there must be much more people out there having the same problem, but if they do not use Garamond Premiere Pro, Helvetica and some others, then they do not recognise the problem. OR / AND the  problem is associated to 64 bit and Windows 7 and not to 32 bit and older Windows versions and MAC versions. I have in mind to chat with Adobe's technicians today. But then I came across the issue here and start here, hoping somebody can help.

I am a bit desperate because my book should have been sent for print a long time ago (there were other obstances of nearly force majeure character) so first a total pc crashdown and then these font problems in these last days is just TOO MUCH.

Could my reflexions lead you or others to see what the bug is about?

I hope you survive my novel long text. But I am no concise type. Thanks for your patience.

Best regards

Dorte

Hello.

I am also having the same problem. I have been packaging this same/similar type of document with the same font wtih CS4/CS5/CS5.5 and now I can not package in CS6 with the error:

"Cannot copy necessary fonts".

Have we come to any sort of resolution?

Thanks for any help.

For me going to your fonts folder worked (/Library/Fonts)

Selecting them all, then right-click 'get info'.

Make sure all are not locked.

And in your font-book, select all your fonts, and click 'resolve duplicates'.

Hope this was helpful.

Problem solved, at least for me!

Peter, thanks for your comments. I had the same problem pop up one day, even after I had packaged other files on the same system with the same version of InDesign without problems. It turned out that two of my fonts were locked. How do you know if your fonts are locked? Do a simple search in the Finder for each font used in your document to see if any of them are locked. If they are (you'll see a small lock on your font icon) then right click > get info > uncheck the "locked" box.

Thanks for the response.  This also worked for me but follow the above instructions carefully.  I did everything except relocking the padlock and still had issues.  Here are the steps for clarity:

1.Go to Font Book -> Right click on troublesome font and click Show in Finder

2. Right click on font name and click Get Info

3. Scroll to the bottom right of the info panel and click on the gold pad lock to unlock (you will have to type in the system admin password).

4. Scroll back up and uncheck Locked.

5. Scroll back to the bottom right of the info panel and click the pad lock to relock. (This was the step that I didn't do before)

After I did the above steps, my files would package just fine. 

When I was done, I went back to the Font Book -> right clicked on a font -> Show in Finder.  Change the list view to icon view and looked for the locked fonts.  These show up with a lock on the bottom left corner of the icon.  Then I followed the steps as outlined above.  I did this on every font that was locked and everything seems to be working fine now.  What a pain....
