Problem in packaging and installing embedded exe in single sis file

Hi,

I have a .pkg file with an embedded .exe (another application) with following lines:
[INDENT]
addFiles = "\"embeddedapp.exe\" - \"!:\\sys\\bin\\embeddedapp.exe\""
postpack.pkg_postrules = addFiles
DEPLOYMENT += postpack[/INDENT]

When I am using selfsigned to package main application in .sis, it gets failed with following error:

[INDENT]
Auto-patching self-signed package.

Patching package file and relevant binaries...

Patching: Non-zero vendor ID (0x) is incompatible with self-signed packages in "embeddedapp_patched_caps.exe", setting it to zero.

Patching: Executable with capabilities incompatible with self-signing detected: "embeddedapp_patched_caps.exe". (Incompatible capabilities: "".) Reducing capabilities is only supported for libraries.


Patching: Unable to patch the package for self-singing.
Use a proper developer certificate for signing this package.

I am not sure why it is patching the embeddedapp.exe file due to incompatible Capabilities. Following are the capabilities defined for embeddedapp .pkg file
[INDENT]symbian:TARGET.CAPABILITY += ReadUserData WriteUserData[/INDENT]


May be Selfsigned don't allow to embed Exes, I therefore tried symbiansigned.com certificate, it packaged successfully without any error, but the installation is getting failed.
