You can't.

First of all .NET applications do not care about bitness. The compilies IL
is agnostic to 32 to 64 bit.

Its the framework which actually runs the IL and compilies to native code
that runs on the client that utlimately determinse bitness.

In order to runs a 1.1 based application in 64 bit you would need to the
destination machine to have a 64 bit version of the 1.1 framework installed.
Unfortunately no such thing exists. The first Framework to be released in
both 32 and 64 bit is 2.0. Hence you will need to rebuild your app using
the 2.0 framework.
