プレミアプロのバージョン 14.9 は、OSをWindouws11へアップグレードして作動するか否か。

[Kazu-Hara]

現在、OSがWindows10の状況で、プレミアプロのV14.9をインストールして使用しています。

PCは、Windows11への更新（11対応のPC）を催促していますが、現在のまま、OSを11へ更新して、

プレミアプロのV14.9が、そのまま使用できますか？　

どなたか分かる方、ご教示のほど、お願い致します。

1. you can install the latest and 1 version prior versions using the cc desktop app. you must have a subscription because previous versions are not available with trials. other versions are revealed after clicking file preferences>apps>tick show older apps (at panel bottom).


2. no other versions are available

Thank you for your advice, but I have a subscription to Premiere Pro and I'm
using an older version, V14.9.

I want to use this Premiere Pro V14.9.

Is there a specific reason why you need to use version 14.9?

[Kazu-Hara]

Thank you for your help.

The reason is that I haven't used Premiere Pro software for almost three
years, so there's a good chance that the operation method has changed in the
latest version, so I would like to continue using version 14.9 for a while.

If you have Microsoft do an 'in place' upgrade (Win11 installed over Win10) not a fresh install on a new or wiped hard drive you SHOULD not notice any difference, since Microsoft takes care to maintain backward compatibility

That is not an absolute guarantee that any specific old program will keep working, but when I did an in place upgrade a year or so ago I had zero problems with any of my existing programs

ADDED

NOTE I have 4 very old IGT Slot games installed (32bit x86 mode on 64bit OS)
I did not have to select a compatibility mode or run as Admin... Win11 just accepted them
So in my experience Microsoft has done a very good job with backwards compatibility

Hey Kazu-Hara,

A Windows FAQ suggests that some apps might be uninstalled during the update (https://adobe.ly/42nXwlj). If you need to have that version of Premiere Pro available, please look into creating a system image in case it gets removed during the update.
