I have concerns about doing it that way.  One item is the race condition.

The gross way to have a program delete itself is to create a batch file 
which delays then does the delete, execute the command interpreter with the 
batch file as a command line argument and then end the program.  That 
"usually" works.  A variant is to create an executable which delays and then 
deletes and execute it but antivirus programs may not be happy with this 
technique.

To have a program delete itself is a bit difficult.  The 2 part article at 
these links discusses the issues and how to do it:
