Firstly, your version of Maple is not supported in Fedora 17. Maple 13 was released several years before Fedora 17 and there are several issues that may cause it not to run. To summarize a some of these:
Maple has historically been supported in Red Hat, Suse and Ubuntu and is supported in Red Hat 6.0 (Fedora 14). However, in RHEL 6.1 and above or Fedora 15 or above, Red hat has implemented a new consistent network naming structure to name their network cards. With this new convention, Maple can no longer be activated and as such, will not run.
There is a workaround for this though, if you don't mind renaming your network drive from em1 to eth0. If you don't mind renaming this drive, then Maple should run just fine. This drive rename is a lot easier than it sounds and can be done using the following steps: http://www.maplesoft.com/support/faqs/detail.aspx?sid=32610
Now the unrelated 32/64 bit license manager issue that you mention is another sticking point, which can usually be remedied by installing the 32-bit libraries for your OS.
However more importantly, even if you do succeed in getting Maple 13 up and running in Fedora 17, there is a much bigger issue, which has been covered in a few Primes posts including: http://www.mapleprimes.com/questions/130220-Maple-15-X86-64-LINUX-Fedora-16-Log2
Long story short, unfortunately, either upgrading to a later version of Maple, or downgrading your OS may be your only options. Sorry that we couldn't be of more assistance.
