Once the database is restored, a couple items need to be considered:

You can get the packages from the unzipped install media in the "SEPM/Packages" folder. you can use 7zip to open the exe, run the exe. they will appear in the "AppData\Local\Temp" in a folder with randomly generated characters. The client installation package consists of two files. One file is named product_name.dat, and the other file is named product_name.info.
