what installer are you using? LOSI has an "unistall.exe" file in the litestep dir (default: C:\Program Files\Litestep)

oamr's installer *is* out of date, LOSI should be used (it still needs to be uploaded).

1. UPGRADE to xp
2. Download LOSI
3. Run the setup
4. follow the prompts
5. done

as for the 1 click zip file, i am developing a LS version that should meet those needs, and be completely portable.
