Acrobat Pro DC 2015（永続ライセンス）を新しいPCで再インストール／再認証したい

[stylish_Rose9432]

Acrobat Pro DC 2015（永続ライセンス）について相談です。

旧PC（Windows）では、現在も Acrobat Pro DC 2015 を
正常に起動・認証して利用できています。

PC入替（HP ZBook / Windows 11）に伴い、
新しいPCで再インストールおよび再認証を行いたいのですが、
うまく進められず困っています。

公式サポートでは「サポート終了製品のため案内不可」と言われたのですが、
ライセンス自体は失効していない前提で、

・旧PC側で必要な作業（ディアクティベートの要否）
・新PC側でのインストール／認証手順
・実際に同様の移行を行った方の経験談

について、具体的な手順やアドバイスをいただけないでしょうか。

Windows 11 環境での情報があれば特に助かります。
よろしくお願いいたします。

@stylish_Rose9432 honestly, it may work on a Windows 11, but there risks involved and with end of support for it, you are also suspectible for security issues as well. Instead, I would suggest to upgrading and getting the 3-year license to Acrobat. It is fully compatible with Windows 11 and includes modern features like better touch support and improved OCR and the best part is it will receives quarterly security updates too! It isn't like the Acrobat Pro DC 2015 (perpetual license), it is a 3-year license (officially called Acrobat Pro 2024 Classic), meaning after the 3-year term ends, the license expires! You cannot renew it BUT, you can defintely buy another 3-year license! 

If by chance you are a teacher or student (or have a child/spouse who is), the Student & Teacher Edition of the 3-year license is significantly cheaper at retailers like Best Buy, Staples, Amazon, Dell. Granted, if you are a student or teacher, I would check to see if the school has free Adobe applications for you too!! My workplace offers this to our students. 

For example: Staples USA:
Student: Rate at $86
Regular: Rate at $324

Spread that out in 36 months, and either one is a decent rate. Only buy from reputable places.

I’m not asking about security or upgrade options.

Acrobat Pro DC 2015 (perpetual license) is still activated and working on my old Windows PC.
Before deciding on a replacement, I’d like to know:

- Has anyone successfully reinstalled and activated Acrobat Pro DC 2015 on Windows 11?
- If it fails, is the blocker OS compatibility, activation servers, or installer limitations?

Real-world experiences would be appreciated.
