Unpacking WebEXE

have someone came accross the wonderful application Webexe. Like chm help files, it will also embed the user html files in a single exe file. The generated exe files is packed with aspack2.12. Its quite easy to unpack that packer, but i am not able to run the unpacked apps. It will pop error message that the file is corrupted. I think that its due to html data. How can i manage to run that packed file...
