...it sounds "possibly" like it may have installed the 64bit version on your 32bit OS...(I am assuming you DON'T have Win XP 64bit on your machine)...

My understanding is that Vue 6 automatically DETECTS which OS you have and installs its self accordingly... If it DID install the 64 bit version- that might be the reason- if you haven't already, I would COMPLETELY un-install V6i and then re-stall and "check" the 32-bit version when you re-install-- so as to FORCE the 32bit version installation... IF NOT checked...there would be the possibility that your OS "now thinks" you want the 64bit version again, etc...
