Foxpro 2.6 Distribution Kit Question

I am trying to get an application installation to work that uses the SETUP produced by the SETUP.APP. The first part is easy. It's a regular installation. The second part is data that will be different with each install. I want the SETUP.EXE on the first disk to be able to install a file called DISTRICT.DAT from the third DISK. I was able to modify the SETUP.INF file that the setup.app produced to include a third disk under

[Source Media Descriptions]
"3","Disk 4","DISTRICT.DAT","..\DISK3"

and I also added a line under [Application] that references my file. For example:

[Application]
3, DISTRICT.DAT,,,,,,,, !READONLY,, DISTRICT.DAT,,,, 609482,,,,, !VITAL

This installation set all worked fine!

Unfortunately the size of the file DISTRICT.DAT (609482) will be different for each custom disk 3. Is there a way to tell the SETUP.EXE program to not check the size of the file when installing my data from the third diskette? I have tried replacing 609482 with a 0 and with a blank. Both caused the setup to fail. Any suggestions..

I know I should be using a third party install program and probably will after this experience.. But I need to get this one out quickly!
