Forge server .bat file not lauching server with -Xmx and -Xms variables

So this is weird for me,

I have a forge minecraft server (1.16.5, version 36.2.39) that I was running on few years old windows 10, and it was working perfectly fine. A week ago, I decided to completly clean my PC (hard reset of everything) and reinstall windows 10. I got my server back from pendrive only to discover, that it wasn't launching. After checking logs I saw that windows used wrong version of java: 

latest.log

[11sty2023 17:47:09.097] [main/INFO] [cpw.mods.modlauncher.Launcher/MODLAUNCHER]: ModLauncher running: args [--gameDir, ., --launchTarget, fmlserver, --fml.forgeVersion, 36.2.39, --fml.mcpVersion, 20210115.111550, --fml.mcVersion, 1.16.5, --fml.forgeGroup, net.minecraftforge]
[11sty2023 17:47:09.100] [main/INFO] [cpw.mods.modlauncher.Launcher/MODLAUNCHER]: ModLauncher 8.1.3+8.1.3+main-8.1.x.c94d18ec starting: java version 19.0.1 by Oracle Corporation

Naturally, I downloaded Java 8 and created a .bat file for launching it:

run.bat

"C:\Program Files (x86)\Common Files\Oracle\Java\javapath\java.exe" -Xmx4096M -Xms4096M -jar server.jar nogui
PAUSE

Now, here is the weird part. The .bat file (path is 100% correct) doesn't launch the server and  doesn't create neither log file nor debug file. However, when I remove "-Xmx4096M" and "-Xms4096M", it launched but at a very, VERY slow speed (1GB was assembled at max). I need more RAM assembled for the server to load properly.

1.16.x is not a supported version of forge in this forum.

But your question isn't really related the version of forge you are  using.

C:\Program Files (x86)\Common Files\Oracle\Java\javapath\java.exe"

If java installed itself in the "Program Files (x86)" that means you downloaded the 32bit version of java which doesn't support 4GB of memory (unless it also supports certain tricks).

Download the 64bit version of java.

Thank you, don't know how I downloaded 32 bit java. Now it fully works.
