Am running Red Hat Linux Enterprise v4.0 on a Dell laptop.

I have a .bin file I am trying to execute but whenever I do I get the following message:
"The directory /root/istemp48889484849484/ does not contain enough space to extract temp files. Please specify a temp dir using the -is:tempdir option"

So I check my drive space with df -m and get:
/dev/mapper/VolGroup00-LogVol00 18111 2800 14391 17% /
/dev/hda1 99 9 85 10%

The above seems to tell me that I have 14GB free in the root dir.

So then I tried directing the output to a temp directory on the root drive by typing:
./licensemanager.bin -is:tempdir /tmp

But I get the same error message.

I don't know how much space the temp directory needs to execute this .bin but I can't believe it needs more than 14GB.

Any ideas why I get this message?

The file could be lying about where it is creating files, or why it can't create them. It could be that the directory has the wrong permissions to create the files as the user you're running the .bin file as, for example.

A .bin file is just a plain script, although it usually includes a uuencoded binary archive to be extracted, so there's no standard way in which they work. It might help to know where you got the .bin file from, and possibly even see the file.
