Self decrypting archive - does not work?

I am using the trial version.

I was able to successfully create a self-decrypting archive file using PGP command line, but when I try to "run" the resulting file, I have 2 issues:

1) It seems to only run on 32-bit versions of Windows

2) When running it on 32-bit Windows, it just opens a command prompt window with a cursor moving around randomly all over the window. It does not accept any input as far as I can tell. I would expect it to ask for the passphrase, then decrypt the file afterward. Am I missing something?
