???????
I have no idea what it is you are trying to do here, but there is no such thing as "reinstalling app".
If you try to run a cab installation over an existing installation it will first go through the uninstall procedure (as best as it can, running programs can not be deleted) then install as usual.

Uninstall removes app without installing it again where reinstall removes app and installs it again. I hope this answers your question.

bleah..
ok but i need to see it from setup.dll
uninstall procedure should remove registry entries but if i simply reinstall app it shouldn't remove registry...

If you want to see what someone else's setup DLL does you need IDA (http://www.datarescue.com/) and understanding of ARM assembler.

As for registry it depends: If the registry was added by code in setup.dll then the uninstall function in that DLL should be in charge of removing it.
If the registry was added through the inf file of the cab (not all cabs have setup.dll, it is optional) it will be removed by wceload.exe which processes the cab.
