M Keyboard layout creator 1.4 Vista HPx64

jut saying hi,
looks a very useful site.
I want to change a few keys on my laptop, specifically it is a US keyboard & I want to replace the dollar signwith the British pound sign, & reassin the dollar to say "alt 4" not shift 4 also the Euro sign to alt hash. I tried downloading The Microsoft Keyboard Layout Creator 1.4, but its not working on my lap top - Vista Home premium64. no "screen/virtual keyboard " appears to work on, not when selected from existing keyboards or when starting from new.
any fixes for the sortware , or alternative software.
slill level, basic-int.
thanx

 

i solved my problem , mklx works if the dpi of the screen are left at default settings!
