Application packagers know there are some vendor MSIs that just can't be edited with Wise but can be edited with ORCA. If, in such a case, we want to add a file to the package, we can't with ORCA because ORCA has limitations and can not compress the file. In these cases, you can follow the steps given below to add the file to the package.
Makecab [Source] [Destination]
NOTE: - KEEP GENERATED .CAB FILE WITH THE MSI While Installing the Msi
Limitations: You can add only one file in one cab. So this procedure needs to be repeated if there is more than one file to be added to the package.
To make a CAB file for multiple files run typr "iexpress"...
