Hi there

Hope you are doing well and sorry for the trouble.

As described the PDF file is displayed correctly on some PCs and not on others, Please check for any missing/pending updates for the computer OS and try updating it and check.

Please try to create a new test user profile with full admin rights in Win on the affected machines and try using the application there and check.

Also, share the PDF file in question so that we can check it at our end https://helpx.adobe.com/document-cloud/help/sharing-pdfs.html

You may also go through the help page https://helpx.adobe.com/acrobat/using/pdf-fonts.html and see if that works.
