Sorry to say manually registering the dll files for the PDF and PSD filters didn't work, despite getting the 'successful' message for both. Also, there was no PSDFilter.dll file in the folder. I had to copy it across from v.12, along with a few others that I noticed were missing.

All this said, surely your customers shouldn't be expected to go to such measures to get a program to function properly? I've never even had to tell a Xara product to run as administrator before, let alone try all this malarky.
