By default when you install SunSolaris x86 both 32 bit and 64 bit is provided. When configuring it within VMWare we can also select whether we want to have 32 bit or 64 bit.

Only after that will the Solaris run in 64 bit. Even if you have installed it previously when the bios Virtual machine support is not turned on.
To check if it is running 64 bit, just type:
If it is 64 bit, you will see the output as follows:
