What you'll need:
Your computer, a friend's computer.
Adobe CS5 shares its PDF setting across the applications, so they're read from one hidden folder in the C:.
Download and install
trial version of InDesign from the Adobe website onto your
On BOTH computers, go to Control Panel, Folder Options and click the tab
Show, scroll down a little and click
Show hidden files and folders.
There should now be a folder showing called
ProgramData, navigate to
C:/ProgramData/Adobe/ on your computer. There should be a folder here called
Adobe PDF, this is where the presets are stored. If it is not here, then we need to copy from your friend's computer.
Once the installation on your friend's computer is done, navigate to the same place and copy the
Adobe PDF folder onto a USB stick and paste it into
C:/ProgramData/Adobe/ on your computer.
Fire up your Adobe program and see that your PDF presets are there :)
Hope this helps some people, I spent three days trying to fix this and Adobe themselves were NO help!
