Admin Tip #67: Windows NT Default Installation Path

Hits: Failed to execute CGI : Win32 Error Code = 3

If you want to change where NT expects to find its install files, set:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Sourcepath
and
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Sourcepath

If your CD drive is E: and you are working with an Intel-based machine, the value should be E:\I386 and E:\ respectively.
