No. What you have installed is not .net 2.0 and .net 1.1, but .net 2.0
*framework* and .net 1.1 *framework*. You need them both. These are run
time files needed to run programs written with .net 2.0 and .net 1.1
respectively. If you get rid of .net 1.1, you will be able to run programs
written with .net 2.0, but not programs written with .net 1.1.
