Unzipping files to different folder...

Hi. I am using Winzip and Winzip Self-extractor to do the following:

1- Zip two files. file1.exe and file2.xlsx
2- When the user double click on the auto-extract icon:
a- I want file1.exe to go to the desktop.
b- and the file2.xlsx to go the c:\

I have read articles on the internet but have been un-successful.
If some one could help, I would greatly appreciate it.

thanks.
