Problem


When trying to load certain file types into neoStampa, you may encounter one of the following issues:

  • Error message when opening a PDF/AI:

    Error: file format 'C:\Path\file.pdf' is not valid for this application. Unable to load the file.
  • In the Open File dialog, the formats PDF/AI are not even listed as available options.



At first sight, this may look like the PDF file itself is corrupted or unsupported. However, the real issue is often related to licensing.


Root Cause

neoStampa requires a PostScript license to process and open PDF/AI files.

You can confirm this by checking the installed licenses:

  1. Go to About neoStampa Delta > License.

  2. In the list of activated components, look for PostScript.

  3. If PostScript is missing, the system cannot load PDFs.




Solution

  1. Contact Inedit Software to request an additional PostScript license activation.

  2. After activation:

    1. Restart neoStampa.

    2. Reopen your PDF file.

    3. The error should be resolved, and the file will load correctly.
