Invalid CRC launcher

[AleriyaSama]

Hello! I'm Trying to patch my gunz.exe, default.mrs, model.mrs, is not working only system.mrs any clue's how it get works, btw i'm using 1.5 zlauncher source

Also I tried already to reinstall my windows, disable my windows-defender, etc

That must be because of the ZPatchBuilder that is not building the patch.xml well.
When you compile the ZPatchBuilder you must also compile the ZUpdate with the same cml project as your code, otherwise this will not work.

Hello! I followed your steps but it isn't works

Compile zpatchbuilder zlauncher etc still not working.

Hey!

Your using Visual Studio 2019 yes? The issue is the way the DWORD for CRC32 gets calculated. Switch the values to float. The CRC32 is exceeding the upper limit supported safely in vs2019.

Yes i use visual studio 2019, can you say it maybe in a bit more details, because i don't really understand what you mean, and yes i see a'lot of dword's in the files,

Rebuild updater, then patch builder, then launcher. Use the new Patch builder and launcher.

2 Things.
1.
Comment those lines out (Should have done that already during conversion.)

			//if ( aPatchNode.GetChildContents( &nSize, MPTOK_SIZE) == false)
			//	continue;

2. You should disable HanAuthForClient

3. If you need more help, add me on discord
