I was looking into installing LuaRT 32bit version alongside the currently installed 64bit on the same Windows 11 machine. It doesn't seem like there is currently a good way to do this. When I run the 32bit installer, there's a popup with a button that says "Update to LuaRT 1.8.0 for X86" which implies that the current 64bit version will be overwritten. I closed the popup and nothing was installed since I didn't want to do anything that might corrupt what's currently installed.
Has anyone done this? Is there a way to have both 32 and 64 bit peacefully coexist?
