Ok, so here is what's happening. I'm opening zeroday from minecraft launcher and when I do it gives a "could not create the Java Virtual machine" kind of error. I tried launching from the intent launcher as well but when I do it says in the logs "Invalid Maximun Heap Size: -Xmx5G, The specified size exceeds the maximum representable size". Hoping I could get some help.
ZeroDay Launching Issue
How did u get it to your luncher where do you put the zero day file ??

Sounds like you're using a 32-bit Java, which doesn't allow you to exceed 2GB in memory. Also don't forget the -noverify tag and to link the 64-bit Java executable as shown here: https://intent.store/forum/d/5-zeroday-and-launcher-issues/5

you can download the client files on the website, you don't necessarily need the Intent Launcher
- Edited
RowanStrohm If you have less than 5GB of ram available in your system click 
then adjust
save, and relaunch.
That too ^
And what do i with the files i downloaded
minebuster just run the Intent Launcher v5.1.jar from https://intent.store/launcher and it handles everything
Becuause i dont hear any sound in my game
minebuster In case you didn't hear already, press F3 + T ingame or change texture packs. Double check sound is on in settings.
- Edited
minebuster if you don’t hear sounds it is most likely that the resources of the game were improperly loaded, you can check the language settings and if it is blank then indeed resources are missing.
on my default texture pack it says missing pac mcmeta
and sound still doesn ot work
IntentStore added the Solved tag.
