Contact Adobe Customer Care for License Verification
Reach out to Adobe Support to verify your student license and obtain a direct, authorized installer link.
Because the original student-store download link is no longer available, you cannot reinstall the software manually. Adobe Customer Care can verify your purchase history and issue a secure download link for your specific version.
Using a personal Adobe ID instead of a student email is a common practice, and support agents can ensure your serial number remains properly linked to your personal account during the recovery process.
Locate your original digital receipt from the student store and have your student ID or university enrollment proof ready.
Log into your personal Adobe account on the web. Navigate to the 'Plans and Products' section to find the 24-digit serial number associated with your Adobe Acrobat Pro license.
Visit the Adobe Customer Care contact page. Choose to open a live chat or call support. Explain that a macOS security update broke your application and you need an authorized installer.
Use the secure download link provided by the support agent to install Adobe Acrobat Pro. Enter your serial number when prompted to activate the software.

Frequently Asked Questions
Can I use my personal Adobe ID for a student-purchased Adobe license?
Yes, it is standard practice to link a student-edition license to a personal Adobe ID. As long as you can prove your student eligibility at the time of purchase, Adobe Support will assist you regardless of the email address used.
Why did my Adobe Acrobat stop working after the macOS 10.13.6 update?
System and security updates on macOS often change how applications interact with system files or permissions. Legacy software versions may lose authorization or crash due to these underlying architectural changes.
How can I find my Adobe serial number if the app won't open?
You can find your registered serial number by logging into your account on the official Adobe website. Go to your account management dashboard and look under the 'Registered Products' or 'Plans' section.
What if the student store where I bought the software no longer exists?
If the third-party student store is closed, Adobe Customer Care becomes your primary point of contact. Provide them with any remaining proof of purchase, such as a bank statement or confirmation email, to verify your license.
