Vista/Adobe Reader Hell

Hello,
Trying to open a travel itinerary/confirmation (requires Adobe Reader), but my Vista Home Premium system keeps freezing during the Adobe Reader download process. Have tried uninstalling all versions of Adobe (but I cannot read the itinerary w/o it). I know the forums all say Adobe's not compatible with Vista (I want to cry). What else can I use in this case when Cheapcaribbean.com only lets me see my itinerary by installing Adobe Reader?
Would changing my Internet Explorer version help? I think I have 9?

I am in Vista Hell.

Thanks for any help.
