re-compress an installer

[EP]

I have a third-party installer that I need to use as a nested msi. The installer
contains several .CAB files, and I understand that I need to have an msi
without any cab files (all compressed into the .msi). Can this be done?
(compressing the existing cabs into the .msi).

You can use the Orca tool (part of the Platform SDK) to insert the cab files
into the Cabs table in the MSI; you'll also have to modify the Media and
File tables in the MSI to accommodate the new cabs.

Sure. wimakcab.vbs should help you out - it's available in the platform
SDK.
