ThinApp doesn't support Window Shell Extension application well?

this is the first time i try ThinApp,  i tried to capture the installation of TortoiseSVN1.6.6 ,here is what i did:

1. open ThinApp, did a pre installation scan

2. install TortoiseSVN,

3. did the Post installation scan

4. check all the exe files ThinApp find for me (some exe are not selected by default), set TortoiseSVN.exe as the main file conatining data)

5. build  file(not msi format, not compressed)

then i uninstall the tortoisesvn, restart my computer , try to run the TortoiseSVN.exe ThinApp has built for me, but there's no tortoisesvn menu entries in the windows explorer context menu. Anything wrong in my steps?
