Standalone exe(Script Test 1)

Ok here is what I was working on yesterday for like an hour, ill probably add more features, but right now im experimenting with several different things for different scenarios.
Default setup

-\ 
Ok you can pretty much change the above to you own folders if you change it in the NSIS script. The above is pretty basic.
Ok now here is the script(I wrote this for recuva)
!define NAME "OperaUsb"
!define SHORTNAME "OperaUsb"
!define VERSION "9.2.2.27"
!define FILENAME "OperaUsb"
!define CHECKRUNNING "OperaUsb.exe"
!define CLOSENAME "OperaUsb"
!define ADDONSDIRECTORYPRESERVE "NONE"


;==Program Details
Name "${NAME}"
OutFile "..\..\..\${FILENAME}.exe"
InstallDir "\${SHORTNAME}"
Caption "${NAME} | Standalone"
VIProductVersion "${VERSION}"
VIAddVersionKey ProductName "${NAME}"
VIAddVersionKey LegalCopyright "Nathan9222"
VIAddVersionKey FileDescription "${NAME}"
VIAddVersionKey FileVersion "${VERSION}"
VIAddVersionKey ProductVersion "${VERSION}"
VIAddVersionKey InternalName "${NAME}"
VIAddVersionKey OriginalFilename "${FILENAME}.exe"

Ok I believe that the above is pretty straight forward. If you want remove the options for it to backup any settings if you want just a one time app. If you use a program that uses the registry just put it at the end to delete, and put somewhere in the beggining to backup it if that registry is already present. This is just a basic outline, Ill be trying to add more and make it better real soon. I also believe it is best not to compress the original apps settings like its exe etc, with App compactor found here. Seems to increase loading times and really has not affect with the output file size, only when it unpacks itself will it have an affect.
