Fourth part of a multi-volume RAR set for a Windows 8.1 Pro image, 648 MB in size. On its own it cannot be opened; it must sit in the same folder as the other parts, including the self-extracting first part, before extraction. Once complete, the set should give an installation image that can be written to USB for test installs. If extraction fails with a CRC error, one of the volumes is damaged. Use licensed media for customer installs.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @laptopschematics. Enginerys does not host this file.
