You can't.

When you load a PE into memory, (I assume you're using MapAndLoad from ImageHlp.pas,) it loads the modules into memory and loads the data, but it doesn't go through and realign all the pointers the way the standard Windows Loader does.

The pointers in the app are all going to be relative addresses that don't actually point to what they're supposed to point to.

If you know enough about how RVAs and mappings work, you can analyze the code, but you can't actually execute it.
