You can check for the  Environment variables SystemRoot and Windir
or:

1. Use an installer than determines system directories. As an example, to 
use the HJInstal (http://www.freebyte.com/hjinstall) application mentioned 
the other day

"If you want to copy files into the Windows directory use the syntax 
<copy files -WinDir>
To copy files into the system directory use
<copy files -SystemDir>"

2. Read the Registry key 
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRoot

3. Roll your own routine using the GetSystemDirectory or 
GetWindowsDirectory API calls
