I guess you could before installing the program change the setting:
CODE
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion]
"ProgramFilesDir"="C:\\Program Files"
to
CODE
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion]
"ProgramFilesDir"="D:\\Program Files"
Then back again if you want to.
