The Extended Kernel project is still active, but the amount of time I have to work on it has dropped to new lows for various reasons.

I assume that my question will be a little stupid, but: is there a way to trace the reason why application fails to start with extended kernel installed? It crashes with "not a valid Win32 application" reason. Please let me know what information I need to collect (and how to). 

UPD: WGC is an x86 application and is supposedly compiled with newer compiler versions, that's why it crashes. win32 WoT client crashes because x86 KERNEL32 lacks of newer functions.

I tried to run the latest version of Deemix Server on Windows Vista and it give me this error:

 

deemix-server.exe - No se encuentra el punto de entrada  diálogo  No se encuentra el punto de entrada del procedimiento GetActiveProcessorCount en la biblioteca de vínculos dinámicos KERNEL32.dll.

If we translate it to english, it tells that can't find the entry point of the procedure GetActiveProcessorCount in the dinamic library Kernel32.dll. Was this included in the KernelEX? I answered in the topic about latest software for Vista exkernel how to use it without installation, just local redirection so you have all the dlls inside the folder of the applications and .exe.local files. I somewhere read that it's necessary a modification on the registry, but don't know what to modify.

in the mega folder you will find a file named "DLLredirectionenabler.reg"

merge it and then restart the system

I finally found it. I'm trying to get the chromium working and Waterfox working. Chrome gave me an error in the execution, and Waterfox.exe tells that it's not a Win32 valid application. I know that you can easily edit it, but I need an alternative to the CFF explorer.

Exactly, Chromium browsers give an error 0xc0000005.

I don't know if the extended kernel has any impact on java jdk 16 but it installs and works! (i doubt that oracle still cares about vista but java 8 still receives updates that work on vanilla vista)

I don't know if you can actually use it to develop things (jdk = java development kit) but minecraft 1.17 won't run without it (thank god that multimc exists because the native launcher won't load)

Without JDK?.. Why would the game require JDK while most applications rely on Runtime Environment (JRE)?

yea, i was surprised too

i don't know why it requires JDK but that's what i have installed

I am sorry to interrupt this discussion, but what you guys can say about stability of Vista with Extended Kernel?
Thinking of installing it, but is it stable enough for day-to-day use, or i should stick to vanilla Vista?

Never try installing Extended Kernel on systems that were installed using localized media (e.g. using Russian version of Vista). So you should install en-US version first, go through Extended Kernel installation procedure and install Russian MUI in the end.

JDK 16 bundles JRE 16; Java compiled apps will just use the JRE, as pointed out by @SigmaTel71   ...
AFAIK, Oracle no longer supply standalone JRE installers past JRE 8 (8u291 is the latest official release);
as you might already know, 32-bit support was also dropped past 8  ...

I guess @winvispixp should try AdoptOpenJDK. It has a little better performance and still allows to install JRE separately.

Thanks for that  ; also nice to see that 32-bit support hasn't been abandoned by them  ! However, 

https://adoptopenjdk.net/releases.html?variant=openjdk16&jvmVariant=hotspot

suggests only Windows2012r2 or later is supported (?) ...

Some people reported that it works on Windows 7 and its server equivalent as well.

It does, as the Eclipse 2020-12 IDE does call win7 functions through its JRE. I believe it's using JRE 14 or 15. Worked perfect.
