I have 3 XP Profiles - ALL with ADMIN priviledges.

Had the same issue, installed on one profile, went to install it on another profile, and it prompted for a new install.

I thought GREAT - would prefer separate libraries for each profile, but it installed fine on the other profile - but stopped the orig profile from working?!

Might try to copy across the LW fodlers to the new profile and try from there.

<Also get the error each time I start it now - "could not create registry key" Might try a uninstall / reg clean / re-install>
