Disk limit exceeded

I am building lab at my home and trying to install ASM (VE). The error message i get while installing the license is as below.

 

01071008:3: Provisioning failed with error 1 - 'Disk limit exceeded. 16188 MB are required to provision these modules, but only 10296 MB are available.'

 

Can anyone help me with what needs to be done.

 

Thanks!
