Problem with Print Booklet in Indesign

I need to create a 64 pages book (33 spreads?), and I have a problem with the option "print booklet" because it keep adding blank pages and I don't know how to fix it.

If there are any blank pages in your 64 page doc make sure you check Print Blank Pages under Print Settings>General. When you impose for a booklet page 1 and 64 will be combined into a spread so there will be 32 spreads.

You can try Acrobat's Booklet feature as Bob suggests, but there is no Perfect Binding/Signature options. There's also no Creep setting
