Moo0 Video Converter - First project!

This is my first project, and I'm in trouble...

I'm trying to portabilize this app (not found in internet).
I've written this codeline:

In AppInfo.ini:

[Format]
Type=PortableAppsFormat
Version=0.0

[Details]
Name=Moo0 VideoConverter Portable
AppId=Moo0VideoConverterPortable

[Version]
PackageVersion=0.0
DisplayVersion=0.0

[Control]
Icons=1
Start=VideoConverter.exe

[Launch]
ProgramExecutable=Moo0VideoConverter\VideoConverter.exe

In Launcher.ini

[Launch]
ProgramExecutable=Moo0 VideoConverter\VideoConverter.exe

[Activate]
Registry=true

[FileWrite1]
Type=Replace
File=%PAL:DataDir%\settings\VideoConverter.reg
Find=%PAL:LastDrive%\\
Replace=%PAL:Drive%\\

[RegistryKeys]
Moo0_VideoConverter=HKCU\Software\Moo0\Moo0 VideoConverterc

Results:
The program was created and run correctly (GOOD!).
The settings are stored portably (GOOD!).
If I open a video from Menu\File the program run and convert the video correctly (GOOD!).
IF I DRAG A VIDEO ON THE FORM, THE PROGRAM DOESN'T START CONVERSION (BAD!!!).

What's appened, how can I correct the mistake?
Thanks
