How to execute 32bit executables on 64bit system?

[Reg Clemens]

I had a system failure here (which we dont need to go into), and have
reinstalled Fedora-11/64.

Now I cant execute 32bit executables.

I know I had to set something when I installed Fedora-11/64 previously
to get this to work, but cant remember what it was.

Can someone remind me of what I need to do.
