Constructor does not Recgonise CD Image

[TradeDraft]

When I try and Load the Game I get an Error Saying:

Error = Constructor CD Image must be in Drive

Check the contents of the file "SETTINGS\INSTALL.DAT" (or "CONSTRUC\SETTINGS\INSTALL.DAT"). It should say something like InstallPath=D:. You can do that by looking at the file from a computer or by going to the DOS command line and entering type CONSTRUC\SETTINGS\INSTALL.DAT``. If it's D:, check the output of the command line tool mountand see what drive letter the CDROM drive is (it should be D: by default in DOSBox Pure). If it's something else thanD:, you can either edit the file or change the drive letter of the mounted CDROM by going to the command line and entering REMOUNT D: E:` (to switch CD from D: to E:). Changing the drive letter needs to be done every time before starting the game so editing the file is better.

I changed the Drive Letter to what it has here:

but I still got the Same Message.

This what is in the install.dat file:

[PATHS] Installation=Full MainPath=C:\CONSTRUC CDPath=C:\CONSTRUC\CD GFXPath=C:\CONSTRUC MusicIniPath=C:\CONSTRUC\SETTINGS UniVBEConfigPath=C:\CONSTRUC\SETTINGS InstallPath=D: MultiLingual=Yes

So what have I done wrong?
