I used to have a msi with its cab file embedded simply using
<Media Id="1" Cabinet="cab1.cab" EmbedCab="yes" />
And I got a single msi file, which is good.
Now a new requirement is to sign this cab file using a microsoft web application, and they only accept cab files.
So is it in some way possible to generate this unembedded cab file, with wix or manually, sign it, and only then resume the build process to embed it ? Or will I get stuck with an external cab file now ?
