Fonts not found when opening document

Hello ​@defaultixp247q3vk0c 

I hope you are doing well, and thanks for reaching out. We’re sorry for the trouble you had.

This issue occurs because the PDF returned from the e‑signature workflow does not have the fonts embedded. When Acrobat cannot find or substitute the required fonts (for example, Helvetica or Arial), the content may display incorrectly or appear completely blank. Adobe confirms that PDFs relying on system fonts instead of embedded fonts can fail on other machines, especially after automated processing such as digital signing.

• Open the PDF in Adobe Acrobat
• Go to Menu > Properties > Fonts
• Check whether Helvetica / Arial are listed as Embedded or Embedded Subset.

If a font is not listed as embedded, Acrobat depends on the local system to supply it, which is why the file opens blank on some computers.

Also, ensure that you are on the latest build of Acrobat: 25.001.21184 Planned update. Feb 06, 2026. Check for any pending updates by navigating to Menu > Help> Check for Updates. Install the updates, restart the app and the machine, and try again.

Let us know how it goes.

Regards,

Anand Sri.

Recreate and resend the documents with fonts embedded (Export/Save as PDF → enable Embed fonts), or change the document to a standard embedded font before sending for signature.
Also make sure Adobe Acrobat/Reader is updated.

Once fonts are embedded, the signed files will open normally.
