Need Help with SFX

[AssasinCross]

Is there any way to make SFX reads our path location from a registry file?

Example

ABCTools.exe is in D:\ABCTools

HKCU\Software\ABCTools\AppData while AppData is "D:\ABCTools\ABCTools.exe"

I want to make it into a SFX file that extract everything to the application folder.
