Last Version of Software for Windows 8.1

[yoltboy01]

LibreOffice 25.8.0.4 works on Windows 8.1

 

You need to drop the „LaunchCondition“ Table with Orca. After that, the installer will install the suite. All apps seem to work without any issues. So, they could have kept 8.1 support but decided to end both 7 and 8 simultaneously. The suite doesn‘t work on Windows 7 (even with VxKex)

Yes, also on 8.0

So do you have a compiled release for Windows 8/8.1, of Firefox ESR?

In case anyone was wondering how the current Office status is on Windows 8.1:

I installed the latest Microsoft 365 (v2509) on Windows 8.1,which indeed is the 31th Post-EOL Feature Update (v2301) for this System and ... Surprise -> it works!

The new icons match very well with the OS. I like them. Look for yourself tho:

In terms of stability, I would recommend using Office 2024 LTSC. It is supported until 2029 (when Premium Assurance ends for NT 6.3) and includes modern standards yet excluding Copilot (which is great in my opinion)

Good question!

I installed Microsoft 365 (Word, Excel, PP, OneNote). The Image did not contain Outlook but I can test it later for you.

In general, you definitely need to activate before using, since I noticed that Word and Excel tend to crash without proper pre-activation. PowerPoint requires some dlls from Windows 10 to work. 
 

by the way, I noticed that 365 does no longer work on 1507/1511 as well. Here, I receive the same errors as on 8.1. I guess Microsoft won‘t make an official statement regarding older Windows 10 versions.

I tested the latest 146.0a1 Nightly and FF itself does launch using the modifications bymjd79 on the previous page

but it is unable to load any website. Maybe some problem with the patched GetProcessAffinityMask function.

The latest ESR 140.4.0 still works however.
