Indesign could not package document X .. cannot create package folders?

Where are trying to package to? If it's a write protected drive / folder that would explain it.

We are not mind readers... 

Which OS & version? 

Which version of InDesign? 

Now, do you have any special characters in the file path(s)? 

Do you have write rights for the destination location? 

Have you updated anything - hardware or software - OS or InDesign? Have this happened before?

I've moved this from the Using the Community forum (which is the forum for issues using the forums) to the Indesign forum so that proper help can be offered.
