I believe you need to install the Java Advanced Imaging (JAI) ImageIO JARs to be able to read and write TIFF files.

But is JAI a 32-bit set-up/limit? I am looking for a 64-bit solution so i can use more memory.

There are no 64 bit native binaries for JAI and from what I've read it's unlikely there will ever be any but I believe it is possible to use the package in pure Java software only mode which will then run on a 64 bit JDK. I assume there will be some performance hit (possibly huge) for doing this else why would they supply the binaries in the first place.
There's an article here which explains a bit more about this:
