edit icad file

I am reinstalling bricscad on a new computer. I use Bricscad with Eagle point and i am getting an error saying "cant open "C/program files(x86)/Eagle Point software/EGPT/Program/cfasti.dll" for execution.
to correct this i need to delete the last line in the icad.lsp file. when i do this i get a message that access is denied. how do i fix this.
