Hi.

Take a look to the following links:

Appeon 2020 multi-browser problem in window 11 (22H2)

PowerServer 2020 application does not work on browser on Windows 11 22H2 | Appeon

Powerbuilder 2019 R3 (and Powerserver Web) are not supported in windows 11. You may be able to make it work, but if you encounter any issue you won't get support except if you can reproduce it to windows 10. Also be aware that PowerServer 2020 is obsolete and has a End of Mainstream Maintenance date set to 22/01/2026.

okay, thanks for your reply

so i should upgrade then ? to 2022 ?

problem is - what will that mean the users that are working on the old version have to do ?

Powerserver included in PB 2021 and later version is a totally different product. It won't create a web application. It allows you to create a cloud application. If you are not aware of this change, take a look to the following link: PowerServer deployment - - What's New (appeon.com). Also have in mind that new powerserver doesn't support mobile and can run only in windows. Finally you should investigate what happens with licenses as I believe that new powerserver requires to buy new licenses (you cannot upgrade those you had for Powerserver 2020 but you should clarify that point by asking appeon staff).

In long term, upgrading will be "required"...

Andreas.
