InstallAware creates setup files with 7zip using "solid" mode.
In this mode it is not possible to replace a file in the archive
after setup is created.
Is it possible to build the setup without using solid mode?
We need this option in order to replace the release notes file inside the archive after the setup was tested.
You should not modify the package once it is built ... even swapping out a single file will break your installer, as checksums will not longer match what is compiled into the MSI database and so the install will fail ...
