The solution is to use a different switch “-envexe” that is used to modify a different copy of Ghostoem32.exe. This information is included in the PDF file accompanyiong the Recovery Kit.
When customizing GhostOEM32 you must use the switch -envexe in conjunction with other OEM customization switches.
The syntax for this switch is as follows: -envexe=fullpath
where fullpath is the full path of a copy of GhostOEM32.exe that is not currently running. GhostOEM32.exe has to be the last part in the named file path.
GhostOEM32 -envexe=c:\folder\GhostOEM32.exe –oemfile
