If it is an extremely old version like Klemen said then there won't be a fix or support for it. All related programs/softwares will have moved on. Old versions die off/have to just accept whatever the current support is/was at that point but they may not be available to download anymore. Realistically if you want to use mcreator/mod the game you will need to start doing it on the more recent versions of blockbench/mcreator/minecraft
MCreator 1.5.2 is 10 years old, this is an unsupported version.
Use the latest release for last Minecraft versions instead
I don't have this thing
I have 32-bit computer
1.20.6 not support 32 bit
I love old versions :
1.5.2, 1.6.4, 1.7.10, 1.12.2...
I wait for message
