How do I resolve pdf2image: No such file or directory

[Support]

Q" I licensed PDFTron PDF2Image, and have been using it successfully
with Ubuntu version 9.04. We've been experimenting with upgrading our
servers, and noticed that it's no longer working after migration to 74-
bit Ubuntu 10.x. In particular, when I try to run the software by
entering the command ./pdf2image, it says:

-bash: ./pdf2image: No such file or directory

More details: I tried installing from scratch using the following:
(1) wget http://www.pdftron.com/downloads/pdf2image.tar.gz
(2) gunzip and tar
(3) cd into pdf2image
(4) ./pdf2image

When I run the exact same sequence on Ubuntu 9.04, it works as
expected.
Is this a problem you've seen before? do you know how to resolve it?

A: Are you running 64-bit version? In this case could you please make
sure that you have standard 32-bit libs installed?
For example:

apt-get install ia32-libs

in ubuntu is what I did to get it running..
