I'm trying to create a Vista Ultimate 64-bit SP1 slipstream disc. Each time, I'm getting "CabLib Extract ERROR while extracting files from cabinet archive: Corrupt cabinet." My Vista Ultimate retail disc has been copied to the hard drive and I've downloaded the standalone Vista SP1 file (Windows6.0-KB936330-X64-wave0.exe) twice with no indication of error. Each time I attempt the slipstream I end up with the same error message listed above, which aborts the process. System info: vLite 1.2 RC Clean install of Vista Ultimate 64-bit RTM release with no patches (no SP1) Intel Core 2 Quad Q9300 @ 2.5GHz 8GB RAM with 50GB+ free hard drive space Suggestions appreciated.
