We are still on PowerBuilder 2019R3 and PowerServer 2020 and our application was working fine.   We normally use kernel32.dll to access some windows functions.   Some of our users upgraded with the latest Windows 11 24H2 version and the application stopped working.  We went to the forums and they say that now, with the latest Windows 11 version, Microsoft prevents applications to run from inside the browser.   I went and removed those karnetl32.dll functions but we are still facing issues running our application on those machines.   I know that Appeon does not support PowerServer 2020 on Windows 11, but I would like to know if there is a workaround to fix this issue.

Thanks

We fixed the problem also in Windows 11 Home.

We found that we can also install the Group Policy Editor in that Edition of Windows 11.

The application is again fully functional.  Thanks a lot!

Thank you very much Kai Zhao

This is a good solution for my PowerServer 2020 running on Windows 11 24H2

PowerServer 2020 application does not work well on Windows 11 24H2 | Appeon

However, the Group Policy Editor is only present in Windows 11 PRO Edition.

What about Windows 11 Home Edition?  Do you have any idea on how to work on these policies?

Hi, this fix worked fine with Windows 11 22H2.

This week, we have a problem with the current release of Windows 11 24H2.  Our application is crashing.

As I have read, this Windows update has a lot to do with security.

For example, in our application we were able to access windows functions in libraries like kernel32.dll.

With this windows update, we are not longer allowed to use windows system libraries, and that is one of the reasons our application was crashing.

We will keep this post updated once we remove all access to windows system libraries to see if our application run fine again.

Thanks!
