I don't think there is one, however there's a trick to fool it.
Taken from an old post I made.
Using FAKECD and some tips posted earlier I had success!
Here's what I had to do.
Create a directory called LB2_207F on your computer. You can create this
anywhere, just make sure you don't go over 8 characters for this directory
name. You'll also need a disk drive with at least 1.8 Gig of free HD space.
You'll be able to claim a lot of it back later.
Using Windows Explorer copy the entire contents of both LB2 CD's to this
Copy FAKECD.EXE to your C:\WINDOWS directory (do a web search for FAKECD.EXE
it's everywhere, if your really stuck I'll Email it to you). You can put
this file any where on your hard drive(s). Just make note of where it is
and refer to it properly in the next step.
Using Notepad or Edit, you'll need to modify your C:\AUTOEXEC.BAT file.
Make sure you have Windows started when you edit this, if you run a dual
boot system. Add the following to it.
C:\WINDOWS\FAKECD.EXE C:\LB2_207F /L:J
*Note - You can substitute C:\LB2_207F for any directory, just refer to it
properly when you modify AUTOEXEC.BAT.
Also I choose J for my drive letter, but any unused and free drive letter
will do. I choose J, short for Janes.
Your system now has a new, fake, CDROM J: drive.
Using Windows Explorer, go to the J: drive and run the SETUP.EXE file. This
starts the LB2 install.
Make sure you do a Custom Install and select Full Copy (420MB). Note the
directory location of the install.
After it's installed, go to the J: drive and delete EVERY file EXCEPT the
Keep each and every *.tre file
Keep the jlb2cd01 and jlb2cd02 files
Keep the map directory and it's entire contents.
Once you've done this first clean up, copy the *.tre files from J: to your
Longbow2 install directory you noted ealier. Once copied you can remove the
*.tre files from J: (cutting and pasting would be quicker).
This should leave the J: drive with just the map directory and it's contents
and the two jlb* files.
Start LB2 and enjoy a CD Free experience!
PS - If someone knows where Longbow hides its CD Install information
(registry or *.ini file) we could probably lessen the amount of copy disk
space required for the install part!
