This sounds suspiciously like an "all rights reserved"... i.e., no license at all. Users who obtain a copy of the program already have the right to run it for any (legal) purpose, and already have the right to study how it works and adapt it. Redistribution in whole or in part, modified or not, is already prohibited by copyright law.
The only way you could prevent someone from running the program, studying it, or modifying it is if you got the user to agree to a contract in order to get the software. An EULA is a type of contract.
There's nothing wrong with not having a license agreement. Just stick "Copyright I.M.A. Programmer 2007 - 2010" prominently.
