installation - Winrar sfx deletes files too early -

i'm trying build sfx (self extracting archive) using winrar.

i'm using vs2008 build setup.exe , myapp.msi. if setup.exe executed checking launches myapp.msi

i'm using sfx options make extraction quiet , make extract temp folder:

it seems winrar deletes msi right after setup.exe launched. setup.exe can't find msi , crashes. there way fix this?

// edit:

i solved problem (a while ago) calling myapp.msi instead of setup.exe:

the msi not exit until installation finished.

7-zip provides tools creating sfx installers, give try :)
